What is 80 percent of a number whose 20 percent is 90?

Answer 1

To find 80% of a number, you can multiply the number by 0.8. Given that 20% of the number is 90, we can find the total number by dividing 90 by 0.2. This gives us a total number of 450. Therefore, 80% of 450 is 360.

Answer 2

If 20 percent of the number is 90, then the number is equal to (90 / 20) x 100 = 450. To find 80 percent of this number, multiply it by 0.8. In this instance, 450 x 0.8 = 360
