Question

Claire had 4 1/6 feet of string. She used some string to hang out decorations. Now she has 1 5/6 feet of string left. How much string did claire use? Draw a model and solve.

Answer 1

Length of string used by Claire = 7 / 3 feet

Explanation:

Given:

Length of string Claire in starts =
`4(1)/(6)` feet

Length of string Claire in end =
`1(5)/(6)` feet

Find:

Length of string used by Claire

Computation:

Length of string Claire in starts =
`4(1)/(6)` feet = 25 / 6 feet

Length of string Claire in end =
`1(5)/(6)` feet = 11 / 6 feet

Length of string used by Claire = Length of string Claire in starts - Length of string Claire in end

Length of string used by Claire = [25 / 6] - [11 / 6]

BY taking LCM

Length of string used by Claire = [25 - 11] / 6

Length of string used by Claire = 14 / 6

Length of string used by Claire = 7 / 3 feet
