28 is what percent of 50
Ans:
"Percent" means "parts in 100". x% means x parts out of 100 parts.
28 out of 50 means "28 parts out of 50 parts". Now how much is that out of 100?
Since 100 is twice 50, 28 parts of 50 would be (28 * 2 = 56) parts in 100.
So 28 is % of 50
Remember that:
x% of a number a means (a * x/100}
To express a fraction (x/y), which means "x parts in y" as a percentage, you just
have to multiple (x/y) by 100 i.e. (x/y)*100. In this question, (28/50)*100 also
gives 56%
Hope this helps :)
