Simplify negative 3 over 4 divided by 2 over negative 8.

Answers

Answer:

3

Step-by-step explanation:

−3/4÷2/−8=?

In the second fraction, move the negative sign from the denominator to the numerator and the value remains the same.

The equivalent equation is

−3/4÷ −2/8=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator, leaving the negative sign on the numerator, and changing the operation to multiplication. Then the equation becomes

−3/4× −8/2=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

−3× −8/4×2= 24/8

Since 24 divided by 8 equals 3 then,

24/8 =3

Therefore:

−3/4÷ 2/−8= 3

a^2 = 144

a = √144

a = 12

So, the answer is 12, which means we pick D
