Solution: We have given that each covering is 15 windows long you need to calculate how many window coverings are necessary to span 50 windows.
The operation is a simple division: 50 ÷ 15 gives the number of times that 15 is contained in 50.
The result is 50÷15 = 3.33.
So, you need more than 3 coverings, and so take the next whole number, i.e. 4.
So, the answer is 4
