Kayla can make 50 ribbons for the show using 32 feet ribbon
<u>Solution:</u>
Given, Kayla's making ribbons for school spirit day a roll of ribbon is 32 ft long And for each individual ribbon she needs 0.64 ft
We have to find how many ribbons can she make for her old show.
Number of ribbons that can be made is found out by dividing total available ribbon by ribbon length required for single ribbon


Hence, Kayla can make 50 ribbons for the show using 32 feet ribbon.
So first find the factors of the denomenatores
14=2 times 7
7=7
21=7 times 3
common one would be having at least one 2, one 7, and one 3
find what numbers can be made by all of them
2 times 7 times 3
2 times 7
7
7 times 3
they are all in it
2 times 3 time s7=42
common denoomenator is 42
