There are 63 students in band. This represents 30% of the grade. How many students are in the entire grade
almond37 [142]

So, the question is 63 is 30% of what number?

That can translate to the equation

     63 = 30% · x     or     63 = 0.3x

Divide by 0.3 and you get x = 210.

There are 210 students in band.
