(1 point)
-147/75
147/75
9
-9

Answer 1

To solve this problem, you'll need to follow the order of operations, which is parentheses, multiplication/division from left to right, and then addition/subtraction from left to right.

First, let's simplify the multiplication part:
(-4) x (7/5) x (-3/4) = (-28/5) x (-3/4)

Next, let's simplify the division part:
(7/15)

Now, let's multiply the two fractions:
(-28/5) x (-3/4) = (-28 x -3) / (5 x 4) = (84/20)

Finally, let's divide the result by the fraction (7/15):
(84/20) ÷ (7/15) = (84/20) x (15/7) = (84 x 15) / (20 x 7) = 1260/140 = 9

So, the final answer is 9.

Answer: 9
