(-3) / 3/4 x 2/7 x -5/16 / 5/7

1 answer

To simplify the expression (-3) / 3/4 x 2/7 x -5/16 / 5/7, we can follow the order of operations, which is parentheses, exponents, multiplication/division (from left to right), and addition/subtraction.

First, let's simplify the fraction part first: -3 / 3/4
To divide by a fraction, we invert the divisor and multiply:
-3 ÷ 3/4 = -3 x 4/3
= -12/3
= -4

Now, let's substitute this value back into the expression and continue simplifying: -4 x 2/7 x -5/16 / 5/7

Next step, multiply: -4 x 2/7 = -8/7

Now, we have: -8/7 x -5/16 / 5/7

Invert the divisor and multiply: -8/7 ÷ 5/7 = -8/7 x 7/5

Cancel out the common factors between the numerators and denominators:
(8/1) x (1/5) = 8/5

Therefore, (-3) / 3/4 x 2/7 x -5/16 / 5/7 simplifies to 8/5.
