Answer 2

Answer:

The answer is

-4.5454545455%

step-by-step explanation:

Where |old value| denotes the reference's exact number; this choice was taken so that it would function correctly for both high and low values of old value and Current Value. Keep in mind that relative change and % change have the same meaning. Depending on the current and old values, it may be a percent rise or a percent drop. If the new value exceeds the previous value, the outcome will be favourable and we will experience an increase. The outcome will be negligible and we will experience a decline, however, if the net amount is less than the previous value.

A decrease from 220 to 210 denotes a negative change (reduction) -4.5454545455%

To get the % change, substitute the supplied values in the equation listed below 

Percent change $=\frac{New-Old}{old} *100$%

Percent change $=\frac{210-220}{220} *100$%

$=-\frac{-10}{220} *100$

$= -4.5454545455%$% $(decrease)$

The new number is 210, while the previous value was 220. Because the new value is less than the previous value, we have a negative change (drop) of -4.5454545455 percent in this instance.

The percentage rise or reduction among two values represents the percentage difference. When evaluating an old value to a new value, use this converter.
