Question

Identify the number in the box:
(i) $\frac{16}{24}=\frac{4}{\square }$

(ii) $\frac{28}{36}=\frac{-7}{\square }$

(iii)$\frac{18}{54}=\frac{\square }{6}$

(iv) $\frac{-21}{36}=\frac{\square }{4}$

Answer 1

(i) $\frac{16}{24}=\frac{4}{6}$ $\Rightarrow \frac{16÷4}{24÷4}=\frac{4}{6}$

(ii) $\frac{28}{36}=-\frac{7}{9}$ $\Rightarrow \frac{28÷(-4)}{36÷(-4)}=\frac{-7}{9}$

(iii) $\frac{18}{54}=\frac{2}{6}$ $\Rightarrow \frac{18÷9}{54÷9}=\frac{2}{6}$

(iv) $\frac{-21}{36}=\frac{-7}{4}$ $\Rightarrow \frac{-24÷9}{36÷9}=\frac{\frac{-7}{3}}{4}$.
