Question

Find:-

$7.8÷1000$

Answer 1

When we divide a number by $1000$, the answer is obtained by shifting the decimal in the number to the left by three digits

Given $7.8÷1000$

$$\begin{gathered} =\frac{78}{10}÷1000 \\ =\frac{78}{10}\times \frac{1}{1000} \\ =\frac{78}{10000} \\ =0.0078 \end{gathered}$$

Hence, the required solution is $0.0078$.
