Question

write rational numbers with standard form =33/77,64/-20​

Answer 1

$\huge \underline \bold \red{SOLUTION}:$

$= > \frac{33}{77} = \frac{3 \times 11}{7 \times 11} = \frac{3}{7} \\ = > - \frac{64}{20} = - \frac{16 \times 4}{5 \times 4} = - \frac{16}{5}$

here in 1st number we have 11 common so we should numerator and denominator with 11

and similarly in second one we have 4 as common so you divide it by 4

hope it helps you
