To solve this expression, we can simplify step-by-step using the properties of operations and rules for multiplying and dividing signed numbers.
First, let's simplify the multiplication:
(-4) × (7/5) × (-3/4) = (-4) × (-3) × (7/5) × (1/4)
= 12 × (7/5) × (1/4) [Since (-4) × (-3) = 12]
= (12 × 7 × 1) / (5 × 4)
= 84 / 20
= 4.2
Next, let's simplify the division:
4.2 ÷ (7/15) = 4.2 × (15/7) [Since division is equivalent to multiplication by the reciprocal]
= (4.2 × 15) / 7
= 63 / 7
= 9
Therefore, the solution to the expression (-4) × (7/5) × (-3/4) ÷ (7/15) is 9.
Use the properties of operations and rules for multiplying and dividing signed numbers to solve:
