when he sells a house for

\text{GH₵ }690,000

. Calculate the percentage of his commission.

$15.0\%$
$10.0\%$
$7.5\%$
$5.0\%$

Solution:

Percentage

Percentage commission

=\frac{\text{GH₵ }103,500}{\text{GH₵}690,000} \times 100\%

Note:

1. The zeros (0) at the end of 100 and 690000 cancels each other

2. The zeros (0) at the end of 103500 and 6900 cancels each other

3. 69 divides itself 1 , and 1035, 15 times
