Question

Replace $\text{'}\oplus \text{'}$ by the correct number.

$\frac{5}{\oplus }=\frac{35}{91}$

Answer 1

Finding the missing number

Given : $\frac{5}{\oplus }=\frac{35}{91}$

Using the cross product method,

$$\begin{gathered} 5\times 91=35\times \oplus \\ \frac{5\times 91}{35}=\oplus \end{gathered}$$

It can be written as

$$\begin{gathered} \oplus =\frac{5}{35}\times 91 \\ \oplus =\frac{1}{7}\times 91 \\ \oplus =\frac{91}{7} \\ \oplus =13 \end{gathered}$$

Therefore,$\frac{5}{13}=\frac{35}{91}$
