Question

A dressmaker cut a piece of ribbon One-fourth of an inch long from a piece Seven-sixteenths of an inch long. What is the length of the remaining piece of ribbon? Three-sixteenths of an inch Six-twelfths of an inch Eight-twelfths of an inch StartFraction 11 over 16 EndFraction of an inch

Answer 1

Three-sixteenths of an inch.

Explanation:

Given:

Total Length of ribbon =
`(7)/(16) \ inch`

length of piece of ribbon cut =
`(1)/(4)\ inch`

We need to find the remaining length of piece.

Solution:

To find the remaining length of piece we will subtract Amount of piece of ribbon cut from Total Length of ribbon.

framing in equation form we get;

remaining length of piece =
`(7)/(16)-(1)/(4)`

Now to solve the same we will make the denominator common by using L.C.M.

remaining length of piece =
`(7*1)/(16*1)- (1*4)/(4*4) = (7)/(16)-(4)/(16)`

Now the denominators are same so we will subtract the numerators.

remaining length of piece =
`(7-4)/(16) =(3)/(16)\ inch`

Hence Remaining length of the piece is
`(3)/(16)\ inch`.
