Question

How long is 33 inches added to 4 feet 7 inches?

Answer 1

It is `88` inches or `7` feet and `4` inches.

Explanation:

As each feet has `12` inches, `4` feet have `4×12=48` inches. Hence `4` feet and `7` inches are `48+7=55` inches

and adding `33` inches to `4` feet and `7` inches is `33+55=88` inches.

Now as `12` inches equal to one foot and `88=7×12+4`, we can also write `88` inches as `7` feet and `4` inches.

Answer 2

`7 " feet " and 4 " inches "`

Explanation:

You cannot add number which are in different units, so something has to be converted.

Let's convert `" " 33` inches to feet and inches and then add.

`1 " foot " = 12 " inches"`

`33` inches = (24 + 9 ) inches = 2 feet and 9 inches (24+9)

`color(white)(xxxxx)"feet" color(white)(xx)"inches"`

`color(white)(xxxxxx)4 color(white)(xxxx)7`
`color(white)(xxx.x)ul(+2 color(white)(xxxx)9)`
`color(white)(xxxxxxx) color(white)(xxx)cancel16" "`add the inches first. It is more than 12!!
`color(white)(xxxxxx) ul(1color(white)(xxxx)4)" "` 16 inches to feet and inches. `(16 = 12+4)`
`color(white)(xxxxxx) 7color(white)(xxxx)4" "` now add the feet

Answer: `7 " feet " and 4 " inches "`
