Question

If x is to 9 as 8 is to 12, then x is equal to _____

Answer 1

x=6

Explanation:

We can write ratios to solve

x 8

----- = -----------

9 12

Using cross products

12x = 8*9

12x = 72

Divide by 12

x = 72/12

x =6

Answer 2

`x=6`

Explanation:

This is basically just a ratio in disguise. Ratios can be represented as fractions, and we can write these ratios to be equal to each other.

`(x)/(9) = (8)/(12)`

We can solve for x using the cross products property:

`9\cdot8=72\\\\72/12=6`

Hope this helped!
