Question

Fill the box with missing number.

$\frac{4}{17}=\frac{\square }{34}$

Answer 1

Given : $\frac{4}{17}=\frac{\square }{34}$

Using the cross-product method.

$$\begin{gathered} 4\times 34=\square \times 17 \\ \frac{4\times 34}{17}=\square \end{gathered}$$

It can be written as ,

$\square =\frac{34}{17}\times 4$

Divide $34$ by $17$, the result value is $2$.

$$\begin{gathered} \square =2\times 4 \\ \square =8 \end{gathered}$$

Therefore, $\frac{4}{17}=\frac{8}{34}$
