Question

How can you solve for x in the proportion 7/8 = x/24

A. Set the sum of 7 and 8 equal to the sum of 24 and x, and then solve for x.
B. Set the sum of 7 and 24 equal to the sum of 8 and x, and then solve for x.
C. Set the product of 7 and 8 equal to the product of 24 and x, and then solve for x. D. Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x.

Answer 1

answer Choice D this is what is known as cross multiply

Answer 2

Correct option is:

D. Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x.

Explanation:

We have to determine how we can solve for x in the proportion:

7/8=x/24

Multiplying both sides by 8×24,we get

`(7)/(8)* 8* 24=(x)/(24)* 8* 24`

i.e. 7×24=x×8

As we can see, we have to set the product of 7 and 24 equal to the product of 8 and x and then solve for x

Hence, Correct option is:

D. Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x.
