Question

What is the difference of the fractions? Use the number line to help find the answer.
7

Answer 1

C.) -7/5

Explanation:

To subtract fractions, we need to have common denominators. So first, we will change -1 1/5 to -6/5.

Now we will change the denominator of both -6/5 and 1/2 to 10.

We now have:

5/10 and -12/10

5-12=-7

So the answer would be -7/5

If we want to use the number line, we would first find 5/10 (1/2) on the graph and count down (to simulate subtraction) 12 units since we are subtracting by 12. :))
