Question

What fraction is the other race?

Answer 1

`(4)/(9)`

Explanation:

Firstly, we need to find a common denominator. I used 36

Next we can convert each fraction to that demoninator

`(2)/(9) *(4)/(4) =(8)/(36) \\\\(1)/(12) *(3)/(3) =(3)/(36)\\\\(1)/(4) * (9)/(9)=(9)/(36)`

Next we can add all of these fractions together.

`(8)/(36) +(3)/(36) +(9)/(36) =(20)/(36) =(5)/(9)`

Lastly, we can subtract this fraction from 1 to find our answer

`1-(5)/(9) =(4)/(9)`

Answer 2

Solve for x

Explanation:

`(1)/(4) + (1)/(12) + (2)/(9) + x=1`
