How to determine the original number to the nearest tenth?
These are the specified parameters:
a number is decreased by 8%, the result is 79.
Suppose, a number = x
a number - 8% a number = 79
x - 8/100 x = 79
100/100 x - 8/100 x = 79
92/100 x = 79
x = 79 × 100/92
x = 7900/92
x = 85.8
So these numbers are 85.8.
