Question

$\text{Convert}12\frac{6}{7}\text{to improper fraction}?$

• A. $\frac{90}{7}$
• B. $\frac{50}{7}$
• C. $\frac{90}{10}$
• D. $\frac{40}{10}$

Answer 1

The correct option is A

$\frac{90}{7}$

$Mixedfraction=Wholenumber\frac{Numerator}{Denominaor}$
$Improperfraction=\frac{(Wholenumber\times Denominator)+Numerator}{Denominator}$

So,
$12\frac{6}{7}$$=\frac{12\times 7+6}{7}$$=\frac{90}{7}$
