find least common denominator and rewrite the fractions
lets use 24: 24/3 = 8, 24/4 = 6, 24/8 = 3
so 2/3 = 16/24
1/4 = 6/24
4/8 = 12/24
now add them together:
16/24 + 6/24 + 12/24 = 34/24 which becomes 1 and 10/24 reducing to 1 and 5/12

Write the number in scientific notation: 60,000
To write a number in scientific notation, first, write a decimal point in the number so that there's only one digit to the left of the decimal point.
Next, count the number of places the decimal point would need to move to get back to the original number.
The number of spaces to get back to the original number is the exponent.

Find the multiplicative inverse, or reciprocal, of . 5 over 9
Final answer:
The multiplicative inverse or reciprocal of the fraction 5/9 is 9/5, which is the result of flipping the numerator and denominator.
Explanation:
The multiplicative inverse, or reciprocal, of a fraction is another fraction in which the numerator and denominator are flipped. For the fraction 5 over 9, the multiplicative inverse is found simply by reversing the numerator and the denominator, turning it into 9 over 5.
To illustrate this with an example, let's consider the fraction ½. The reciprocal of ½ is 2, as their product equals 1 (1/2 x 2 = 1). Similarly, the reciprocal of 5/9 will be such that (5/9) x (9/5) = 1.
Hence, the reciprocal of 5/9 is 9/5.

For the bake sal, Sandra baked 4 trays of cookies, with 12 cookies on each tray. Teo baked 6 pans of brownies and divided each pan into 8 piece. How many items will Sandra and Teo have for sale in total? Write a mathematical question (order of operations), hen solve your expression to find the answer.
Plz help, u will be awarded 20 points if u help.
Sandra and Teo will have a total of 96 items for the bake sale. We find this by first multiplying the number of trays Sandra baked by the number of cookies per tray, then multiplying the number of Teo's brownie pans by the pieces per pan, and finally adding our two results together.
Explanation:The subject of the question is Mathematics, specifically it is an arithmetic problem involving multiplication and addition. It is a middle school grade level question.
To solve it, we need to multiply the number of trays Sandra baked by the number of cookies on each tray. So, 4 (trays) * 12 (cookies) = 48 cookies.
Next, multiply the number of brownie pans Teo baked by the number of pieces each pan was divided into. That is, 6 (pans) * 8 (pieces) = 48 brownies.
Finally, to find the total number of items for the bake sale, we simply add our two results: 48 (cookies) + 48 (brownies) = 96 items.

E goes from (4,8) to (1,2) which equals a 1/4 scale factor ( put lower number over higher number so X = 1/4 and Y = 2/8 which reduces to 1/4)
so H needs to be reduced by 1/4
