Answer 1

I just took this quiz and the correct answer is actually 1 9/10

Explanation:

Answer 2

To answer this question, two steps are taken:

The first step is to match the denominators of the fractions to facilitate the operation. Multiply
`(11)/(5) *2` in the numerator and denominator.

Then it is
`(22)/(10) m`.

The second step is to find out how much blue fabric you have compared to yellow. For that, 31 is divided by 22.

So that's equal to 1.409.

Then you need
`1^(41/100)` more blue fabric than yellow

To check the answer add
`(11)/(5) + (11)/(5) * (41)/(100)  = 3.102` which is approximately
`(31)/(10) m`
