Joaquin needs twelve and one-half feet of floor trim to go around the inside of a closet. He has one piece of trim that is three and three-fourths feet and another piece of trim that is three and one-half feet. How many more feet of trim does Joaquin need for the closet?

5 1/4

Step-by-step explanation:

Joaquin needs twelve and one-half feet of floor trim to go around the inside of a closet.

This is written Mathematically as: 12 1/2 feet

He has one piece of trim that is three and three-fourths feet

= 3 3/4 feet

Another piece of trim that is three and one-half feet.

= 3 1/2 feet

How many more feet of trim does Joaquin need for the closet?

This is calculated as the:

Total number of feet of trim he needs - sum of (3 3/4 + 3 1/2)

12 1/2 - [ 3 3/4 + 3 1/2]

12 1/2 - [ 3 + 3 + (3/4 + 1/2)]

12 1/2 - [ 6 + ( 3 + 2/4)]

12 1/2 - [ 6 + 5/4]

12 1/2 - [ 6 + 1 1/4]

12 1/2 - [ 7 1/4]

12 - 7 + ( 1/2 - 1/4)

5 + ( 2 - 1/4)

5 + 1/4

= 5 1/4

Hence, Joaquin need 5 1/4 more feet of trim
