The Basic Formula
To find out what percentage one number is of another, you can use the formula:
[
text{Percentage} = left( frac{text{Part}}{text{Whole}} right) times 100
]
In this case, the part is 70 and the whole is 125. Plugging in those numbers, we get:
[
text{Percentage} = left( frac{70}{125} right) times 100
]
Calculating this gives:
[
text{Percentage} = 0.56 times 100 = 56%
