Question

The set department has a 5 foot board. They cut 2 segments that are `1 1/2` foot each. How much of the board is left?

Answer 1

`1 1/2 = 3/2`
so two segments of `1 1/2 = 2 * 3/2 = 3`
remaining board length = `5 - 3 =2`foot

Answer 2

2 feet

Explanation:

`color(green)([5 color(white)(..)color(blue)(ubrace(-1 1/2- 1 1/2))]) feet`
`color(white)("dddddd.d")color(blue)(uarr)`

`color(white)("ddd")color(blue)("The 2 segments")`

`color(white)("dddddd.d")color(blue)(darr)`
`color(green)([5 color(white)(..)color(blue)(- color(white)("..d")obrace(3))color(white)("dd"2/2)]) feet`

`color(white()`

`2` feet
