Like fractions of the fractions $\frac{3}{7}$ and $\frac{4}{9}$ would be

• A. $\frac{27}{63}and\frac{28}{63}$
• B. $\frac{12}{27}and\frac{12}{28}$
• C. $\frac{27}{63}and\frac{36}{81}$

Answer 1

The correct option is A $\frac{27}{63}and\frac{28}{63}$

To get to the same denominator, we multiply the first fraction with 9 and the second fraction with 7 respectively.

$\frac{3\times 9}{7\times 9}=\frac{27}{63}$

$\frac{4\times 7}{9\times 7}=\frac{28}{63}$
