The question
Question: Mia sells $1,500 of car parts.
She earns 6% commission.
How much commission does she earn?
1 Find the commission
Percent means out of 100.
So 6% is 6 divided by 100: 0.06.
The point moves 2 places to the left.
6% = 6 ÷ 100 = 0.06
The commission is 6% of $1,500.
"Of" means times: 0.06 times $1,500.
That is $90.
commission = 0.06 × $1,500 = $90
To multiply decimals: first 6 times 1500, as whole numbers.
That is 9000.
Then count the decimal places: 2.
So it is 90.00.
6 × 1500 = 9000
2 decimal places: 90.00
Careful!
6% is not divided by 6.
It is 6 out of every 100.
Careful: not $1,500 ÷ 6 = $250 ✗
So the commission is $90.
2 Check
Let's check: $90 divided by $1,500 is 0.06.
That is 6%, the commission rate.
So the answer is right!
$90 ÷ $1,500 = 0.06 = 6%
Let's look back.
First: find the commission.
Last: check.
Answer
Careful: not $1,500 ÷ 6 = $250 ✗
