What percent of 90 is 50
andre [41]
To re-phrase this: 50 is a certain percent of 90.

this can be written mathematically as 50=x%*90

let's divide both sides by 10:

5=x%*9

and divide both sides by 9:

\frac{5}{9} =x%

which in decimals is approximately 0.56 (but not exactly).

so 0.56=x%

and the x then 56

so 50 is approximately 56% of 90:

exactly 56%of 90 is 50.4
