If there are 30 children in a class and 3 are absent what is the percentage of absent children and what is the percentage of children present

If you want to do %'s as ratios, then you can think of it as:

part/total = %/100
In this case the part that is absent is 3 and the total is 30, so:

Multiply both sides by 100.

The percent of students absent is 10%. That means that 100%-10%=90% were present.
However, if you want practice. The number of students present is 30-3=27. So the proportion you would need to solve is.

Reduce and multiply both sides by 100 to see if you get 90%.
Happy Calculating!!! Hope that helped.
