Answer 2

To solve this expression using PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right):

Step 1: Solve the expression within the parentheses:
-4 * 7/5 * (-3/4) divided by 7/15
= -4 * 7/5 * 3/4 divided by 7/15

Step 2: Simplify the multiplication:
= -4 * 7 * 3 / 5 * 4 divided by 7/15

Step 3: Simplify the multiplication within the division:
= -84 / 5 * 4 divided by 7/15

Step 4: Simplify the division by multiplying by the reciprocal of 7/15:
