Question

What is 20/4 - 8 please help

Answer 1

-3

Explanation:

Multiply and divide {left to right}:

20/4 = 5

Add and subtract {left to right}:

5 - 8 = -3

{Negative + Positive = Negative}

Fraction:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(20/4, 8/1) = 4

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

`((20)/(4) *(1)/(1) )-(8)/(1) *(4)/(4) )=[?]`

Complete the multiplication and the equation becomes

`(20)/(4) -(32)/(4) =[?]`

The two fractions now have like denominators so you can subtract the numerators.

Then:

`(20-32)/(4) = (-12)/(4)`

Since -12 divided by 4 equals -3 then,

`(-12)/(4)=-3`

Therefore, -3 is the correct Answer or Fraction form = -1/3
