Question

28 divided by 7 = _________

• A. 28 − 7 − 7 − 7 − 7
• B. 28 − 7
• C. 28 + 7
• D. 28 + 7 + 7 + 7 + 7

Answer 1

The correct option is A 28 − 7 − 7 − 7 − 7

Division is known as repetitive subtraction.

Let’s look at the table below, where 7 is repeatedly subtracted from 28.
$\begin{array}{cc}1.& 28-7=21\\ 2.& 21-7=14\\ 3.& 14-7=7\\ 4.& 7-7=0\end{array}$

7 is subtracted four times from 28 to get 0.

Therefore,
28 divided by 7 = 28 − 7 − 7 − 7 − 7
