Question

Josie is determined the length of the fabric she has left for a project. Fabric A is 2/5ft.Long. Fabric B is 3/4 ft. Longer than fabric A. Fabric C is 7/10 ft. Shorter than fabric B. What is the total length of fabric A, B, and C

Answer 1

A =
`(2)/(5)` ft

B =
`(23)/(20)` ft

C =
`(9)/(20)` ft

The total length of fabric A , B ,C = 2 ft

Explanation:

The length of fabric A =
`(2)/(5)` ft

The length of fabric B =
`(3)/(4)` ft +
`(2)/(5)` ft

B =
`(15 + 8)/(20)` ft

B =
`(23)/(20)` ft

The length of fabric C =
`(23)/(20)` ft -
`(7)/(10)` ft

C =
`(23 -14 )/(20)` ft

C =
`(9)/(20)` ft

The total length of fabric =
`(2)/(5)` ft +
`\frac{23}                {20}` ft +
`(9)/(20)` ft

The total length of fabric =
`(8 + 23 +9)/(20)` ft

=
`(40)/(20)` ft

= 2 ft

Hence the total length of fabric A , B ,C = 2 ft Answer

Answer 2

The length of Fabric A = 2/5 ft , Fabric B = 23/20 ft, Fabric C = 9/20 ft

Explanation:

The length of the fabric A = 2/5 ft

The length of the fabric B = (
`(3)/(4)  + (2)/(5)`) ft

Hence, the length of fabric B is :

(
`(3)/(4)  + (2)/(5)`) =
`(3(5) + 2(4))/(20)  =  (23)/(20)` ft

Now, the length of fabric C =
`((23)/(20)  - (7)/(10) ) ft`

⇒
`((23)/(20)  - (7)/(10) ) ft` =
`(23(10) - 7(20))/(200)  =  (9)/(20)`

Hence, the length of : FABRIC A = 2/5 ft

FABRIC B = 23/20 ft

FABRIC C = 9/20 ft
