Question

Jeremy has two 7 foot long boards. He needs to cut pieces that are 15 inches long from the boards. What is the greatest number of 15 inch pieces he can cut from the two boards ?

Answer 1

Answer:

The greatest number of 15 inch pieces he can get is 5

Step-by-step explanation:

Given

Length of boards = 7 foot.

Size of pieces needed = 15 inches

We want to calculate the greatest number of 15 inches pieces he can get...

First, the length of the board has to be converted from foot to inches

If 1 inch = 12 foot, we can get the equivalent of 7 foot by multiplying both sides by 7.

So, 1 foot = 12 inches becomes

7 * 1 foot = 7 * 12 inches

7 foot = 84 inches

To calculate the greatest number of 15 inch pieces he can get, we have to divide the length of the board by 15.

Number of pieces = 7 foot / 15 inches

Number of pieces = 84 inches / 15 inches

Number of pieces = 5.6

By rounding down 5.6 , we get the greatest number of 15 inch pieces he can get.

Hence, the greatest number of 15 inch pieces he can get is 5

Answer 2

the answer would be 33. so the first thing you want to do is turn 7 feet into inches. if 12 inches is equal to 1 foot then 7 feet are equal to 84 inches. then add another 84  inches which will equal 168. the you would want to divide 168/15 which gives you 33.6. this mean that 33 (separate numbers) 15 inches of board from two boards.

hope I was able to help and that my explanation made sense. : )
