Question

What is the sum of the fractions? Use the number line to help find the answer. A. -2 B. -4/5 C. 4/5 D.2

Answer 1

The answer is B.

Explanation:

You solve it using the number line. Starting with the point at 3/5 then, you have to go backwards by 7 steps which is -4/5.

You can ignore the denorminator as all the denorminators are the same.

Answer 2

-4/5

Explanation:

The parentheses can be removed immediately since they do not affect the outcome in this problem.

then we have:

3/5 - 7/5 = -4/5
