Always use this formula to find a percentage:
<span>% / 100 = Part / Whole</span> replace the given values:
40 / 100 = Part / 150
Cross multiply:
40 x 150 = 100 x Part, or
6000 = 100 x Part
Now, divide by 100 and get the answer:
Part = 6000 / 100 = <span>60</span>

subtract 4x from both sides
3x=9
divide 3
x=3
the number is 3

It is always important to go through the given problem first to get a concept of the requiremement. Then all the information's available from the question has to be noted down in such a manner that there would be no need to look at the question while solving.
Total number of students wearing jeans = 10
Total number of students wearing shorts = 9
Total number of students wearing capris = 2
Then the total number of students surveyed by Mrs Lane = (10 + 9 + 2)
= 21
Now percentage of students wearing shorts = (9/21) * 100
= (3/7) * 100
= 300/7
= 42.85 percent
So a total percentage of 42.85% of the students were wearing shorts.
