Question
$4.7 ÷ 100 =$ _____.
✓
Answer
Given, $47+100=\frac{47}{10}\times\frac{1}{100}$
$\big[\because\text{reciprocal of}\ 100=\frac{1}{100}\big]$
$=\frac{47}{1000}=0.047$
Hence, $4.7+100=0.047$
$\big[\because\text{reciprocal of}\ 100=\frac{1}{100}\big]$
$=\frac{47}{1000}=0.047$
Hence, $4.7+100=0.047$
