Question

Maya has a piece of ribbon. She cuts the ribbon into 4 equal parts. Each part is then cut into 3 smaller equal parts. If the length of each small part is 35 cm, how long is the piece of ribbon?

Answer 1

`420` `cm`

Explanation:

if each small part is `35` `cm`, and there are three of those, multiply `(35)(3)` OR add `35+35+35`

you get
`105`

you now multiply `(105)(4)` OR add `105+105+105+105)` because that piece was one of four pieces

you get
`420` `cm`
(don't forget to add the unit!)

TO CHECK, divide

`420` divided up into `4` pieces
`(420/4)`

you get
`105`

that piece is then cut up into `3` smaller pieces, so divide `105` by `3`
`(105/3)`

you get
`35`
