Question

How do you calculate the percent change of 63 to 105?

Answer 1

The percentage change `=color(green)(66.67%`

Explanation:

The initial value `= 63`

The final value `= 105`

The change `= color(blue)(42`

The percentage change `=` (change in value) / (initial value) `xx 100`

`=color(blue)(42) / 63 xx 100`

`=color(green)(66.67%` (rounded off to nearest hundredth)

Answer 2

Percentage change is `66 2/3%`

Explanation:

The change from `63` to `105` is given by `105-63=42` (i.e. the latter figure minus earlier figure).

For percentage change, we should divide the change by earlier figure and then multiply by `100`.

Hence percentage change is `42/63xx100` (dviding by `21`)

= `(2cancel42)/(3cancel63)xx100`

= `200/3=66 2/3%`
