Question

Which of the following shows 18 divided by 6?

• A. 18 + 6 + 6 + 6 + 6 + 6
• B. 18 − 6 − 6 − 6 − 6 − 6 − 6
• C. 18 − 6 − 6 − 6
• D. 18 + 6 + 6 + 6

Answer 1

The correct option is C 18 − 6 − 6 − 6

Division is known as repetitive subtraction.
Let’s look at the table below, where 6 is repeatedly subtracted from 18.

$\begin{array}{cc}1.& 18-6=12\\ 2.& 12-6=6\\ 3.& 6-6=0\end{array}$

6 is subtracted three times from 18 to get 0.

Therefore,
18 divided by 6 = 18 − 6 − 6 − 6
