Question

Megan made a paper chain that was 4m long. Mason’s chain was 479 cm long. Who’s was the longest? By how much?

Answer 1

Masons is longer

Explanation:

4m=400 cm

479cm=4.79 m

I'm pretty sure you could answer the rest.

Answer 2

Look below

Explanation:

Let's start by converting 4 m into cm:

`4m * (10^(2)cm)/(1m)`
`= 4*10^(2)cm=400cm`

Since Megan's chain is only 400 cm long, Mason's chain is longer by 79 cm.
