To solve this expression, we follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
First, let's simplify the expression inside the parentheses: (−3/4) × (7/15)
To multiply fractions, we multiply the numerators together and multiply the denominators together.
(-3/4) × (7/15) = (-3 × 7) / (4 × 15)
= -21 / 60
= -7 / 20
Now we substitute this value back into the original expression and perform the remaining steps:
(-4) × (-7/20) = 28/20
= 7/5
So the simplified result of the expression is 7/5.
