Answer:
A class of 60 children
3/10 were absent
So we’re trying to find how many pupils are here (kids).
So lets use percentage.
Percentage means out of a hundred so 3/10 is 30/100.
Multiply 10 on each numerator/denominator and you’ll get 30/100.
Now 30/100 is 30 percent.
We are to find 30 percent of 60.
18 pupils are absent.
We’re trying to find who’s here so
60 - 18 = 42
42 pupils are present
