Answer: Jennifer will need 10 tapes.
Explanation:
There are two units of measurement in the question – meters and centimeters.
Each tape is 25 m or 2500 cm long.
First, we need to derive the number of ribbons that Jennifer can cut from each tape.
2500 / 110 = 22.72
We round this number down to the nearest whole number, which is 22, since the excess tape (80 cm) cannot be used to create more ribbons.
Therefore, Jennifer can get 22 ribbons from each tape.
Second, we need to determine the total number of tapes required to make 200 ribbons.
200 / 22 = 9.09
We round this answer up to the nearest whole number, which is 10, since Jennifer needs more than 9 tapes to complete the task.
9 tapes will only give a total of (9 x 22) 198 ribbons.
