3.7 >
> 
Step-by-step explanation:
Andrea has
yards of purple ribbon.
That means length of purple ribbon is = 3 +
yards
In decimals length is = (3 + 0.875)
= 3.875 yards
She has
yards of blue ribbon.
So the length of blue ribbon on decimals will be = 3 + 
= 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 >
>
yards (Pink > blue > purple)
