Chapter 1: Q44. (page 20)

Evaluate the value of $x$ and name the property used in each step:
$5 \cdot \frac{1}{5} = x$

Short Answer

Expert verified

The solution of the expression is $x = 1$ .

Step by step solution

– Given information.

The given expression is:

$5 \cdot \frac{1}{5} = x$

– Write the concept.

Use the Multiplication Property of Equality.

It says, ‘If two expressions are equal to each other and multiply or divide by same number both side by same number, the resulting expression will also equivalent.’

The property of Multiplicative inverse is:

$a \cdot \frac{1}{a} = 1$

– Evaluate the expression.

The expression $5 \cdot \frac{1}{5} = x$ can be solved in below:

$\begin{matrix} 5 \cdot \frac{1}{5} = x \\ 1 = x [Property of multiplicative inverse] \end{matrix}$

Therefore, localid="1648467583338" $x = 1$ .
