To solve for a, we can start by multiplying both sides of the equation by 5 to get rid of the fraction on the left side:
2/5a = 4/15
5 * 2/5a = 5 * 4/15
2a = 4/3
Next, we can divide by 2 to isolate the variable a:
2a ÷ 2 = (4/3) ÷ 2
a = 2/3
Therefore, a = 2/3.
solve for a. simplify if needed. 2/5a = 4/15
a= what
