bot what is (−4)×(7/5)×(−3/4)÷(7/15)

Answer 1

To calculate (-4) × (7/5) × (-3/4) ÷ (7/15), we can simplify the expression step by step.

First, we multiply the numerators together followed by the denominators:
(-4) × (7) × (-3) ÷ (5) × (4) × (7) ÷ (15)

Next, we notice that there are common factors that can be canceled out. We can cancel out two 4s, a 7, and a -7:
(-1) × (-3) ÷ (5) × (1) ÷ (15)

Finally, we multiply the remaining numerators and denominators:
3 ÷ (5) ÷ (15)

Now, we need to divide 3 by 5 and then divide the result by 15:
3/5 ÷ 15 = 3/5 × 1/15 = 3/75 = 1/25

Therefore, (-4) × (7/5) × (-3/4) ÷ (7/15) simplifies to 1/25.
