$\frac{28}{3}$ and $\frac{7}{4}$

• A. $\frac{91}{12}$
• B. $\frac{89}{12}$
• C. $8$
• D. $7$

Answer 1

The correct option is A $\frac{91}{12}$

To subtract fractions, we first need to convert it into like fractions.

$\frac{28\times 4}{3\times 4}=\frac{112}{12}$

$\frac{7\times 3}{4\times 3}=\frac{21}{12}$

$\frac{28}{3}-\frac{7}{4}=\frac{112}{12}-\frac{21}{12}$

$=\frac{(112-21)}{12}=\frac{91}{12}$
