Answer
$\frac{41}{80}$
Work Step by Step
$\frac{7}{10} - \frac{3}{16}$
The least common denominator for the denominators 10 and 16 is 80.
To obtain denominators of 80, multiply the numerator and denominator of the first fraction by 8 and second fraction by 5
$\frac{7}{10} - \frac{3}{16}$ = $\frac{7*8}{10*8} - \frac{3*5}{16*5}$
$\frac{56}{80} - \frac{15}{80}$
Calculate difference of the numerators and put this difference over the least common denominator.
$\frac{56-15}{80}$ = $\frac{41}{80}$
