Answer 1

6030 students passed.

Explanation:

First: We must convert all percentages to decimals:

So, why do we need to convert all percentages to decimals. Well, you don't have to. It's just that it's easier to work with decimals than percentages. So I'll bold out all of the percents in this problem:

Out of 6700 students of a school only 90% passed. Find how many students passed?

So how do we convert that to a decimal. Well...

A: We have to take out the percent sign:

90

B: We have to move the decimal point 2 spaces to the left:

0.90

Now that we have our percent displayed as a decimal, we need to multiply it by the total number of students to find the fraction of people that passed.

So 0.90 [or 0.9] multiplied by 6700

`0.9*6700 = 6030`

So, out of the 6700 students, 6030 passed.
