Cross multiply

10/a = 15/30

10/a(a)(30) = 15/30(30)(a)

Simplify

1/a(a) = 1
15/30(30) = 15

10(30) = 15(a)

Simplify. Combine terms

300 = 15a

Isolate the a. Divide 15 from both sides

300/15 = 15a/15

a = 300/15

a = 20

A) a = 20 is your answer


hope this helps

Hello!

To solve this we will cross multiply the first numerator by the second denominator and then divide by the other value you have besides a, which in our case is 15.

10(30)=300

300/15=20

Therefore, A=20.

I hope this helps!
