Question

How many band uniforms can be made with 131 3/4 yards of fabric if each uniform requires 3 7/8 yards

Answer 1

The question can be read as how many
`3 (7)/(8)` can be made out of
`131 (3)/(4)`


`131 (3)/(4)`÷
`3 (7)/(8)` ⇒ We need to change each mixed number into an improper fraction


`131 (3)/(4)= ([131*4]+3)/(4)= (527)/(4)`

`3 (7)/(8)= ([3*8]+7)/(8) = (31)/(8)`


`(527)/(4)`÷
`(31)/(8)`

`(527)/(4)`×
`(8)/(31)`

`(527*8)/(4*31)= (4216)/(248) =17`

Answer: 17 uniform
