Naomi has been contracted to put decorative lights on the outside edges of a building. She knows that each string of lights she will use has a length of 47 feet. If the outside edges of the building total 1350 feet, what is the least number of strings of light Naomi will need?
A.26
B.27
C.28
D.29
97 / (6 3/4) = 14.37
1350 / 47 = 28.72
To find the answers to these questions, we need to divide the given lengths by the length of each item (spirit ribbons and strings of lights) and then round down to the nearest whole number.
9. Joey has a piece of ribbon that is 97 inches long. Each spirit ribbon is 6 3/4 inches long. To find the greatest number of spirit ribbons Joey can make, we divide the total length of the ribbon by the length of each spirit ribbon:
97 inches ÷ 6 3/4 inches = 14.37.
Since we need to round down to the nearest whole number, the answer is 14.
Therefore, the correct answer is B. 14.
11. The total length of the outside edges of the building is 1350 feet. Each string of lights is 47 feet long. To find the least number of strings of lights that Naomi will need, we divide the total length of the outside edges by the length of each string of lights:
1350 feet ÷ 47 feet = 28.72.
Since we need to round down to the nearest whole number, the answer is 28.
Therefore, the correct answer is C. 28.
