Question

Reduce to lowest terms

Answer 1

4 ft 5 in

Explanation:

Adding:

`2\ ft\ 8\ in`

+
`1\ ft\ 9\ in`

We get
`3\ ft\ and\ 17\ in`.

`17\ in` can be further converted to
`ft\ and\ in`

As
`12\ in = 1\ ft`

∴
`17\ in =12\ in + 5\ in=1\ ft + 5\ in`

∴ Reduced form is =
`3\ ft\ +1\ ft + 5\ in=4\ ft\ 5\ in`
