Answer 1

Answer:

$1\frac{7}{8}\ in$

Step-by-step explanation:

step 1

Convert mixed numbers to an improper fractions

7.15h tire

$6\frac{5}{8}\ in=\frac{6*8+5}{8} =\frac{53}{8}\ in$

7.15h tire

$4\frac{3}{4}\ in=\frac{4*4+3}{4} =\frac{19}{4}=\frac{19*2}{4*2}=\frac{38}{8}\ in$

step 2

Find the difference

$\frac{53}{8}\ in-\frac{38}{8}\ in=\frac{15}{8}\ in$

step 3

Convert to mixed number

$\frac{15}{8}=\frac{8}{8}+\frac{7}{8}=1\frac{7}{8}\ in$
