on a number line can be found using the
expression |-7 - 3|
ber line can be the one clare used?

Explanation:

Step1: Find a common denominator

The denominators are 4 and 8. The least common denominator is 8. Rewrite $\frac{3}{4}$ with denominator 8: $\frac{3}{4}=\frac{3\times2}{4\times2}=\frac{6}{8}$

Step2: Subtract the fractions

Now subtract $\frac{3}{8}$ from $\frac{6}{8}$: $\frac{6}{8}-\frac{3}{8}=\frac{6 - 3}{8}=\frac{3}{8}$

Answer:

$\frac{3}{8}$
