$95 = \frac{1}{2} n \leftarrow equation$ $95=1/2n larr" equation"$

For this to work the actual value of $n$ $n$ is $190$ $190$

Given that: $95 = \frac{1}{2} n$ $" "95=1/2n$

If half a number is 95 then the number must be two lots of 95.

That is: $95 + 95 = 190$ $95+95 = 190$

Given that: $95 = \frac{1}{2} n$ $" "95=1/2n$

Determine the value of $n$ $n$

Multiply both sides by $2$ $color(blue)(2)$

$2 \times 95 = 2 \times \frac{1}{2} \times n$ $color(brown)(color(blue)(2xx)95 =color(blue)(2xx)1/2xxn)$

$2 \times 95 = \frac{2}{2} \times n$ $color(brown)(color(blue)2xx95 =(color(blue)(2))/2xxn)$

But $\frac{2}{2} = 1$ $2/2=1$ giving:

$190 = 1 \times n$ $190=1xxn$

$\Rightarrow n = 190$ $=> n=190$
