Question

George went to school for 216 days in a full year. If his attendance in 60%, find the number of days on which the school was opened.

Answer 1

Hi

216 days ⇒ 60%
x days ⇒ 100%

60x = 216·100
60x = 21600
x = 21600/60
x = 2160/6
x = 360 days

Answer: 360 days

Answer 2

Given:
days present = 216 days
percentage of presence = 60%

Find the total number of days the school was opened.

216 days is the part of a whole. 60% is the percentage of the part to the whole.

To get the whole, we need to divide the part by its percentage

216 ÷ 60% = 360 days

The school was opened for 360 days.
