Answer 3

Calculation of (4/15 + 2/5) ÷ 2

To solve the given expression, we can follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, let's calculate the sum inside the parentheses: - 4/15 + 2/5 = (4*5 + 2*15) / (15*5) = (20 + 30) / 75 = 50 / 75 = 2/3

Now, we can proceed with the division: - (2/3) ÷ 2 = 2/3 ÷ 2 = 2/3 * 1/2 = 2/6 = 1/3

So, (4/15 + 2/5) ÷ 2 = 1/3.
