Question

ten students in the art class used watercolors. This represents 40% of the students who used watercolors for painting.how many students are in the class?

Answer 1

There are 25 students in the class because ten represents 40% and another ten would equal 20 students or 80%. Half of 40% is 20% and half of 10 is 5 and 80%+20%=100% or 20+5=25.
