Answer:
first question: 6 ribbons
second question: 9 students
step-by-step explanation:
convert 2 feet into inches
2 feet = 24 inches
each ribbon needs to be 3 1/2
if you put 24 into a fraction 24/1
and put it into like terms 48/2
3 1/2 as an improper fraction is 7/2
so 48/2 / 7/2 flip the second fraction or reciprocal
48/2 • 2/7
96/14
6.85714286
so only 6 ribbons because you cannot make quite 7
1/3 of 27 is 9
27/1 / 3/1
