Question

Fill in the blank by using the pattern.

$$\begin{gathered} \left(a\right)(9-1)÷8=-----\left(d\right)(9876-4)÷8=------ \\ \left(b\right)(98-2)÷8=-----\left(e\right)(98765-5)÷8=----- \\ \left(c\right)(987-3)÷8=----\left(f\right)(987654-6)÷8=----- \end{gathered}$$

Answer 1

Observe the pattern-

$$\begin{gathered} (9-1)÷8=1 \\ (98-2)÷8=12 \end{gathered}$$

We can observe that terms are increasing by a digit in each row.

So, the complete table will be-

$$\begin{gathered} \left(a\right)(9-1)÷8=1\left(d\right)(9876-4)÷8=1234 \\ \left(b\right)(98-2)÷8=12\left(e\right)(98765-5)÷8=12345 \\ \left(c\right)(987-3)÷8=123\left(f\right)(987654-6)÷8=123456 \end{gathered}$$
