The new number, 200, is 400 less than the original number. What is the approximate percent change?

Solution:

It is given that

New number 200 is 400 less than the original number

So the original number is 200 + 400 = 600

Here 200 is a third of 600

The percent change can be found by (old number - new number)/ old number

Approximate percent change = (600 - 200)/ 600 × 100

= 400/600 × 100

= 66%

Therefore, the approximate percent change is 66%.

The new number, 200, is 400 less than the original number. What is the approximate percent change?

Summary:

The new number, 200, is 400 less than the original number. The approximate percent change is 66%.
