Question

Convert the given statement into expression form and simplify:

One-fifth of a number minus $4$ gives $3$

Answer 1

Assume $x$ be the number.

One-fifth of the number $=\frac{1}{5}\times x=\frac{x}{5}$

One-fifth of a number minus $4$ $=\frac{x}{5}-4$

Given statement is One-fifth of a number minus $4$ gives $3$ as $\frac{x}{5}-4=3$

Now solving the given statement, we get

$$\begin{gathered} \frac{x}{5}-4=3 \\ \Rightarrow \frac{x}{5}=3+4 \\ \Rightarrow \frac{x}{5}=7 \\ \Rightarrow x=7\times 5 \\ \Rightarrow x=35 \end{gathered}$$

Hence, the required expression is $\frac{x}{5}-4=3$ and whose solution is $x=35$.
