Divide (13.24) ÷ (1.2).

Step: 1

The division ignores the decimal points in dividend and divisor.
⇒ (1324) ÷ (12) = 11.033

Explanation:

We solve the division problem as we normally would with whole numbers.

Step: 2

After division, count the total number of decimal places in the decimal numbers involved:
13.24 -→ 2 decimal place 1.2 -→ 1 decimal place
Add these decimal places together and position the decimal point in the result accordingly.
Divide 13.24 by 1.2 results in 11.033, which has 3 decimal places.

$2a$

Explanation:

To find the total decimal places in a division, add the decimal places of the numbers being divided. 13.24 has 2 decimal place, and 1.2 has 1 decimal place. So, the result will have 3 decimal places: \$13.24 \times 1.2 = 11.033\$.
