You could round 77 to 80 and 65 to 70 and then add 70 and 80 and you will get 150
The problem deals with a division and the rest of it, that is dividing the total amount of pencils into 9 classrooms and the rest, lets express it as fraction:
935/9 = 103 + 8/9
that is, if we multiply 103*9 we get 927 and are 8 pencils left over, therefore, 8 pencils are donated to the library and each classroom gets 103 pencils, in total 935 pencils are donated.

Fraction: 23/100
Decimal: .23
Percent: 23%
Step-by-step explanation:
