Solve for a . Simplify if needed. 2/5a=4/15 (1 point)?

3 answers

To solve for a, first cross multiply:

2 * 15 = 5a * 4

30 = 20a

Then divide both sides by 20:

a = 30/20

a = 3/2 or 1.5

Therefore, a = 1.5.

My apologies for the error. Let's solve it again:

Given: 2/5a = 4/15

First, cross multiply:

15 * 2 = 5a * 4
30 = 20a

Then divide by 20:

a = 30/20
a = 3/2
a = 1.5

Therefore, a = 1.5.
