Anais bought 2 1/2 yards of ribbon.
And she had 2 feet 8 inches left after trimming some curtains.
The first thing to do is to convert all units to inches;
From standard conversion rate.
1 yard = 36 inches
As such 2 1/2 yards of ribbon in inches will be:
= 2 1/2 × 36 inches
= 5/2 × 36 inches
= 5 × 18 inches
= 90 inches of ribbon bought.
Similarly, since 1 foot = 12 inches.
The amount of curtains left after trimming is:
= ( ( 2 × 12 ) + 8 )inches
= (24 + 8) inches
= 32 inches
If Anais bought 90 inches of ribbon and she had 32 inches of ribbon left after trimming some curtains.
It implies that the number of inches of ribbon that Anais used is:
= 90 inches - 32 inches
= 58 inches
Therefore, we can conclude that Anais used 58 inches of ribbon.
