Question

Max bought two deli sandwich rolls measuring 18 inches and 30 inches. he wants them to be cut into equal sections that are as long as possible. Into what length should the rolls be cut? How many section will there be in all?

Answer 1

There would be 8 in all and each roll would be 6 inches

Answer 2

Answer: There are 6 sections in all.

Explanation:

Since we have given that

Length of first deli = 18 inches

Length of second deli = 30 inches

We need to cut into equal sections that are as long as possible.

So, we will find H.C.F. of 18 and 30 = 6

So, the length of first deli should be cut into 18÷ 6 = 3 inches

Length of second deli should be cut into 30÷ 6 = 5 inches.

Hence, there are 6 sections in all.
