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. : )
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
