Question

The screen on Lawrence's new phone is 3.15 centimeters long.What mixed number represent the lenght of the phone screen?

Answer 1

A mixed number is written in a form of
`a (b)/(c)`, where 'a' is a whole number.

One example of mixed number is
`3 (1)/(4)`, read as 'three and one quarter'. As decimal fraction,
`3 (1)/(4)` equals to 3.25

We are given the value of 3.15 and to change this into a mixed number, first note the whole number, which is 3.

We then change the decimal value 0.15 into a fraction and it is
`(15)/(100)= (3)/(20)`

Hence, 3.15 =
`3 (3)/(20)`
