To find out what number 28 is 70% of, we can use a simple mathematical formula. The formula for finding the original number when we have the percentage is:
Original Number = Given Number / (Percentage / 100)
In this case, the given number is 28 and the percentage is 70. Plugging in these values, we get:
Original Number = 28 / (70 / 100)
This simplifies to:
Original Number = 28 / 0.7
Calculating this gives:
Original Number = 40
So, 28 is 70% of 40.
