Question

Express the division facts as repeated subtraction using patterns.

$24 \div 3$

Accepted Answer

Given, $24 \div 3$ .

Since division means repeated subtraction.

Now subtract the number $3$ from $24$ until the remainder or the number of dots becomes $0$ , that is.

Step $1$ $\begin{matrix} 1 & 2 & 3 & 4 & 5 \\ 6 & 7 & 8 & 9 & 10 \\ 11 & 12 & 13 & 14 & 15 \\ 16 & 17 & 18 & 19 & 20 \\ 21 & 22 & 23 & 24 \end{matrix}$ $24 - 3 = 21$

Step $2$ $\begin{matrix} 1 & 2 & 3 & 4 & 5 \\ 6 & 7 & 8 & 9 & 10 \\ 11 & 12 & 13 & 14 & 15 \\ 16 & 17 & 18 & 19 & 20 \\ 21 \end{matrix}$ $21 - 3 = 18$

Step $3$ $\begin{matrix} 1 & 2 & 3 & 4 & 5 \\ 6 & 7 & 8 & 9 & 10 \\ 11 & 12 & 13 & 14 & 15 \\ 16 & 17 & 18 \end{matrix}$ $18 - 3 = 15$

Step $4$ $\begin{matrix} 1 & 2 & 3 & 4 & 5 \\ 6 & 7 & 8 & 9 & 10 \\ 11 & 12 & 13 & 14 & 15 \end{matrix}$ $15 - 3 = 12$

Step $5$ $\begin{matrix} 1 & 2 & 3 & 4 & 5 \\ 6 & 7 & 8 & 9 & 10 \\ 11 & 12 \end{matrix}$ $12 - 3 = 9$

Step $6$ $\begin{matrix} 1 & 2 & 3 & 4 & 5 \\ 6 & 7 & 8 & 9 \end{matrix}$ $9 - 3 = 6$

Step $7$ $\begin{matrix} 1 & 2 & 3 & 4 & 5 \\ 6 \end{matrix}$ $6 - 3 = 3$

Step $8$ $\begin{matrix} 1 & 2 & 3 \end{matrix}$ $3 - 3 = 0$

Hence, the required answer is $8$ .
