Answer:
[tex]1\frac{7}{8}\ in[/tex]
Step-by-step explanation:
step 1
Convert mixed numbers to an improper fractions
7.15h tire
[tex]6\frac{5}{8}\ in=\frac{6*8+5}{8} =\frac{53}{8}\ in[/tex]
7.15h tire
[tex]4\frac{3}{4}\ in=\frac{4*4+3}{4} =\frac{19}{4}=\frac{19*2}{4*2}=\frac{38}{8}\ in[/tex]
step 2
Find the difference
[tex]\frac{53}{8}\ in-\frac{38}{8}\ in=\frac{15}{8}\ in[/tex]
step 3
Convert to mixed number
[tex]\frac{15}{8}=\frac{8}{8}+\frac{7}{8}=1\frac{7}{8}\ in[/tex]
