Question

A book is 0.33 meters long. How many millimeters long is it?

Answer 1

330 mm <33

Explanation:

Answer 2

we know that

`1\ meter=1,000\ millimeters`

so

by proportion

Find how many millimeters are in
`0.33` meters

`(1,000)/(1) (mm)/(m) =(x)/(0.33) (mm)/(m) \\ \\x=1,000*0.33 \\ \\ x=330\ mm`

therefore

the answer is

`330\ mm`
