(ii) denominator 10

Answer 1

(i) Let $\frac{56}{70}=\frac{4}{\boxed{}}$
Clearly, 4 = 56 $÷$ 14
So, we divide the denominator by 14.
∴ ​$\frac{56}{70}=\frac{56÷14}{70÷14}=\frac{4}{5}$
Hence, the required fraction is $\frac{4}{5}$.
(ii) ​Let $\frac{56}{70}=\frac{\boxed{}}{10}$
Clearly, 10 = 70 $÷$ 7
So, we divide the numerator by 7.
∴ ​$\frac{56}{70}=\frac{56\times 7}{70\times 7}=\frac{8}{10}$
Hence, the required fraction is $\frac{8}{10}$.
