To solve this expression, we can use the properties of operations and rules for multiplying and dividing signed numbers.
(-4) × (7/5) × (-3/4) ÷ (7/15)
First, we can simplify the multiplication:
= (-4) × (-3/4) × (7/5) ÷ (7/15)
= (12/4) × (7/5) ÷ (7/15)
= (3) × (7/5) ÷ (7/15)
= (21/5) ÷ (7/15)
Next, we can simplify division by multiplying by the reciprocal of the divisor:
= (21/5) × (15/7)
= (3 * 7) / (1 * 5)
= 21/5
Therefore, the answer is a. 147/75.
