Question

Rewrite the fraction pairs with common denominators

Answer 1

Answer:

a) $\frac{3}{20}$ and $\frac{16}{20}$ = $\frac{19}{20}$

b) $\frac{8}{21}$ and $\frac{18}{21}$ = $1\frac{5}{21}$

c) $\frac{18}{72}$ and $\frac{32}{72}$ = $\frac{25}{36}$

Step-by-step explanation:

a) $\frac{3}{20}$ and $\frac{4}{5}$

$\frac{4}{5}$ x 4 = $\frac{16}{20}$

$\frac{3}{20}$ and $\frac{16}{20}$ = $\frac{19}{20}$

b) $\frac{8}{21}$ and $\frac{6}{7}$

$\frac{6}{7}$ x 3 = $\frac{18}{21}$

$\frac{8}{21}$ and $\frac{18}{21}$ = $1\frac{5}{21}$

c) $\frac{2}{8}$ and $\frac{4}{9}$

$\frac{2}{8}$ x 9 = $\frac{18}{72}$

$\frac{4}{9}$ x 8 = $\frac{32}{72}$

$\frac{18}{72}$ and $\frac{32}{72}$ = $\frac{25}{36}$
