Hi Erika!
To solve this problem, we only need to complete 2 steps! Our goal is to isolate "a" in the equation given.
24/15 = a/35
Step One: Multiply both sides by 35
35*(24/15) = (35)a/35
This cancels out the 35 in the denominator on the right side, setting "a" by itself.
35*(24/15) = 35* (a/35)
Step Two: Calculate
(35*24)/15 = a
840/15 = a
56 = a
The answer to your example problem is 56.
