Question

Fill the box with missing number.

$\frac{10}{14}=\frac{40}{\square }$

Answer 1

Given : $\frac{10}{14}=\frac{40}{\square }$

Using the cross-product method.

$$\begin{gathered} 10\times \square =40\times 14 \\ \square =\frac{40\times 14}{10} \end{gathered}$$

From the above, we can write as

$\square =\frac{40}{10}\times 14$

Divide $40$ by$10$, then result in we will get $4$

$$\begin{gathered} \square =4\times 14 \\ \square =56 \end{gathered}$$

Therefore, $\frac{10}{14}=\frac{40}{56}$
