0.8 of pupils attended school today. If 720 pupils attended school. Find the total number of pupils

If 0.8 of pupils attended school today and 720 pupils attended school, we can set up the equation:

0.8 x Total number of pupils = 720

Dividing both sides by 0.8 gives:

Total number of pupils = 720 / 0.8 = 900

Therefore, the total number of pupils is 900.
