Uma K, Ringmer BN8:
There are 5 x 29.8 children in the school, which is 149 children.
When one child leaves there are 148 children, which is 148 / 5 children per class,
which is 29.6 or 29 3/5 children per class.

Pupils from Holgate Comprehensive School, Hucknall, Nottinghamshire:

Total = 294/5 x 5 = 29 x 5 + 4/5 x 5 = 100 + 45 + 4 = 149
149 - 1 = 148; 148/5 = 293/5

(30 - 1/5) x 5 = 150 - 1 = 149, etc
