Question

117 divided by 2.25?

how to show working

Answer 1

To "show" the steps instead of just using a calculator, we use long division as shown. The final answer is `52`.

Explanation:

`117/2.25`
We set up the long division form. Then move the decimal point to make them both full integers. You then find the highest multiple for the first set of digits, successively subtracting it from the original value and repeating the step until you have no remainder left, or as many digits as you want.

Answer 2

`52`

Explanation:

`"one way is to make the denominator a single digit"`

`"this is done by multiplying the numerator/denominator"`

`"by "color(red)(4)`

`2.25=2 1/4=9/4`

`"and "9/cancel(4)xxcancel(color(red)(4))=9larrcolor(blue)"a single digit"`

`rArr117-:2.25=(4xx117)/9=468/9=52`
