Question

What is 15.36 divided by 4.8?

Answer 1

`15.36-:4.8=3.2`

Explanation:

`15.36-:4.8`

= `1536/100xx10/48`

= `(cancel1536^384)/(cancel100^10)xx(cancel10)/(cancel48^12)` - dividing by `4` and `10` respectively

= `384/10xx1/12`

= `(cancel384^32)/10xx1/cancel12`

= `32/10`

= `3.2`

We can also long divide as follows:

`4.8|bar(15.36color(white)(XXXXXX))|3.2`
`color(white)(XX)ul(144)darr`
`color(white)(xXxX)96`
`color(white)(XXxx)ul(96)`
`color(white)(XXxx)ul(00)`

Note that as divisor has one place after decimal and dividend two places after decimal, then quotient will have `2-1=1` place after decimal.
