Answer:

Step-by-step explanation:

(- 12 / 25) (-10 / 16)

First multiply the numerator then denominator,

Numerator: (-12) x (-10) = 120

Denominator: 25 x 16 = 400

So it will be,

120 / 400

To reduce it, you can start with 2, 4, 5, 8, 10, 20, and 40. The easiest one for me is to divide by 40 because it will give the exact number that I want and I wouldn't have to divide so many time to get to my answer.

Numerator: 120 / 40 = 3

Denominator: 400 / 40 = 10

Final answer will be,

Simplify the following rational expression and express in expanded form.

VladimirAG [237]

Answer:

D m = $-\frac{3}{8}$

Step-by-step explanation:

factor the expressions in the denominator and the numerator to simplify the expression:

=> $\frac{2(-2m + 1)(2m - 1)}{2(2m - 1)(8m + 3)}$

=> $-\frac{2m + 1}{8m + 3}$

to make a fraction undefined, the numerator should be 0, thus, we substitute the values of m from the options into the denominator to make the denominator equals to 0:

=> $-\frac{2m + 1}{8(-\frac{3}{8} ) + 3}$ = $-\frac{2m + 1}{-3 + 3}$ = $-\frac{2m + 1}{0}$
