Question

In 2004, a total of `129,522` criminal offenses were recorded in 2004 in Northern Ireland. If this figure fell by `8.8%` the following year, how many offenses were recorded?

Answer 1

`129,522 - 11,398`

`118,124` offences were recorded.

Explanation:

Calculating the percentage of a number such as

`8.8% " of " 129,522`

is done by using multiplication, division, and subtraction.

First find #8.8% " of " 129,522 by multiplying by the percentage.

`129,522xx8.8%`

`(129,522xx8.8)/100 = 11,398`

The number obtained above is `8.8%` of `129,522`.

Now find the required answer by using subtraction,

Subtract `11,398 " from " 129,522`.

If it fell `8.8%` from the original `129,522` the number of criminal offenses in Northern Ireland during 2004 is:

`129,522- 11,398 = 118,124`

The actual answer is found after calculating the problem above because I wanted to solve this one without a calculator.
