Question

Robert is putting new roofing shingles on his house. Each shingle is 1 2/3 feet long. The north part of the house has a roof line that is 60 feet across. How many shingles can be placed (side by side) on the north part of the house?

Answer 1

Answer: 36 shingles can be placed on the north part of the house.

Explanation:

Given: Length of each shingle =
`1\frac23` feet =
`\frac53` feet.

The north part of the house has a roof line that is 60 feet across.

Then, the number of shingles can be placed on the north part of the house = (Length of roof line in north part) ÷ (Length of each shingle)

`=60/ (5)/(3)\\\\=60*(3)/(5)\\\\=12*3=36`

Hence, 36 shingles can be placed on the north part of the house.
