A problem that requires multiplying two decimals is "If length of a rectangle is 0.2 m and breadth of a rectangle is 0.5 m.Then what is the area of the rectangle ?

What is Multiplication?

Multiplication is an operation that represents the basic idea of adding the same number repeatedly. The multiplied numbers are called factors, and the result obtained after multiplying two or more numbers is called the product of those numbers. Multiplication is used to simplify the task of repeatedly adding the same number.

Manually multiplying numbers to more than a few decimal places is tedious and error-prone. Common logarithms were invented to simplify such calculations, since the addition of logarithms equals multiplication. The slide rule made it possible to quickly multiply the number to an accuracy of about three. Beginning in the early 20th century, mechanical calculators such as the Marchant multiplied numbers up to 10 digits automatically. Modern electronic computers and calculators have greatly reduced the need for manual multiplication.

Here we are taking two decimal numbers 0.2 and 0.5.

If length of a rectangle is 0.2 m and breadth of a rectangle is 0.5 m.Then what is the area of the rectangle ?

Solution: Area of a rectangle = Length × Breadth

[tex] = 0.2 \times 0.5 \\ = 0.10 \: {m}^{2} [/tex]

Here 0.10 is a two decimal number.

To find the number of buttons per jar, divide the total number of buttons (2.134) by the number of jars (12). However, the count of 2.134 buttons is likely incorrect as you cannot have a fraction of a button, indicating a potential typo or miscount.

The question asks how many buttons will be in each jar if Lisa has to sort 2.134 buttons equally into 12 jars. To find this, we need to divide the total number of buttons by the number of jars.

First, let's set up the division equation: 2.134 buttons ÷ 12 jars = number of buttons per jar.

Now, we calculate the number of buttons per jar: 2.134 ÷ 12 = approximately 0.1778 buttons per jar. However, since we can't have a fraction of a button, Lisa likely made an error in counting, as the number of buttons needs to be a whole number. So, assuming there's a typo, and the actual number of buttons is a whole number, Lisa would need to recount her buttons before sorting them.

Once Lisa has the correct number of whole buttons, she could repeat the division process to find the exact number of buttons per jar.

Each jar will contain approximately 0.1785 buttons.

To determine how many buttons will be in each jar, you divide the total number of buttons (2.134) by the number of jars (12). The calculation is as follows: [tex]\( \frac{2.134}{12} \approx 0.1785 \)[/tex]. Therefore, each jar will contain approximately 0.1785 buttons.

In this scenario, the division represents the distribution of buttons into equal portions, with the quotient being the number of buttons per jar. It's crucial to understand the concept of division to solve such problems. In practical terms, if you were to distribute 2.134 buttons equally among 12 jars, each jar would have approximately 0.1785 buttons. This approach ensures a fair and even distribution of the given quantity among the specified number of containers.

Overall, understanding the basic arithmetic operation of division helps solve real-world problems like distributing items equally, and in this case, finding the number of buttons per jar in Lisa's scenario.

The solution to the equation 4(2 + 3c) = 56 is c = 4.

To solve the equation 4(2 + 3c) = 56, we will follow the order of operations (PEMDAS) to simplify the expression and isolate the variable c.

First, we distribute the 4 to both terms inside the parentheses:

4 * 2 + 4 * 3c = 56

Simplifying further:

8 + 12c = 56

Next, we want to isolate the variable c by subtracting 8 from both sides:

8 + 12c - 8 = 56 - 8

Simplifying:

12c = 48

Finally, we divide both sides by 12 to solve for c:

12c/12 = 48/12

Simplifying:

c = 4

Therefore, the solution to the equation 4(2 + 3c) = 56 is c = 4.

Final answer:

The dimensions of the closet are 2.5 feet in length by 2.5 feet in width, given the perimeter is 10 feet and the length is equal to the width.

Explanation:

To solve this problem, we start by understanding that the perimeter of a closet is the sum of all its sides. For a rectangular closet where the length (L) is equal to the width (W), we can express the perimeter (P) as:

P = 2L + 2W

Given that the perimeter is 10 feet and L = W, we can set up the equation:

10 = 2L + 2L

Combining like terms, we get:

10 = 4L

Divide both sides by 4 to find the length:

L = 2.5 feet

Since the width is equal to the length in this closet, W also equals 2.5 feet. Therefore, the dimensions of the closet are 2.5 feet by 2.5 feet.

If Jaylan makes limeade using 3/4 cup of water per 1/5 cup of lime juice.

Given:

Jaylan's recipe: 3/4 cup of water per 1/5 cup of lime juice

Wanchen's recipe: 2/3 cup of water per 1/6 cup of lime juice

Jaylan's recipe:

Unit rate = (3/4 cup of water) / (1/5 cup of lime juice)

= (3/4) / (1/5) [dividing fractions is the same as multiplying by the reciprocal]

= (3/4) * (5/1)

= (3 * 5) / (4 * 1)

= 15/4

= 3 3/4 cups of water per cup of lime juice

Wanchen's recipe:

Unit rate = (2/3 cup of water) / (1/6 cup of lime juice)

= (2/3) / (1/6)

= (2/3) * (6/1)

= (2 * 6) / (3 * 1)

= 12/3

= 4 cups of water per cup of lime juice

Compare the unit rates:

A higher unit rate means there is more water per cup of lime juice which results in a weaker flavor.

Therefore, Wanchen's limeade has a weaker flavor compared to Jaylan's limeade as it has a higher unit rate of water per lime juice.

The cost for 3 pounds of peanuts is found by first determining the cost per pound from the 5 pound price, which is $1.50 per pound. Multiplying this rate by 3 pounds gives us the total cost of $4.50.

If the cost of peanuts varies directly with the number of pounds bought, this means you can find the cost per pound and then use it to calculate the price for any amount of peanuts. Given that 5 pounds costs $7.50, first we calculate the cost per pound:

Cost per pound = Total cost / Number of pounds = $7.50 / 5 pounds = $1.50 per pound.

Now, to find the cost of 3 pounds of peanuts, we multiply the cost per pound by the number of pounds:

Cost of 3 pounds = $1.50 per pound * 3 pounds = $4.50.

Therefore, the cost of 3 pounds of peanuts is $4.50.
