Question

Andrea has 3 7/8 yards of purple ribbon, 3.7 yards of pink ribbon and 3 4/5 of blue ribbon. List the numbers in order from least to greatest.

Answer 1

3 7/8 = 3.875
3.7
3 4/5 = 3.8

least to greatest : 3.7, 3 4/5, 3 7/8

Answer 2

3.7 >
`3(4)/(5)` >
`3(7)/(8)`

Explanation:

Andrea has
`3(7)/(8)` yards of purple ribbon.

That means length of purple ribbon is = 3 +
`(7)/(8)` yards

In decimals length is = (3 + 0.875)

= 3.875 yards

She has
`3(4)/(5)` yards of blue ribbon.

So the length of blue ribbon on decimals will be = 3 +
`(4)/(5)`

= 3.8 yards

And third ribbon of pink color with the length = 3.7 yards

Therefore, the increasing order of the lengths of the ribbons will be

3.7 > 3.8 > 3.875 OR

3.7 >
`3(4)/(5)` >
`3(7)/(8)` yards (Pink > blue > purple)
