How do I solve this?
There are 171 seventh graders eating lunch. This number represents 45% of all of the seventh grades. How many 7th graders are there in the school?
Would I take 171 x 45% and add them together or take 171 X .55 or??

Do you know algebra?
let the number of students be x
.45x = 171
x = 171/.45
x = 380
or do it by the "3 step process"
45% represents 171
so 1% = 171/45 = 3.8
100% = 100*3.8 = 380
