Solution

Step-1: Write $420$ and $520$ in the form of a ratio
$420$ and $520$ $=$ $420 : 520$
Step-2: Simplify the ratio $420 : 520$
$420 : 520$ $=$ $\frac{420 \div 20}{520 \div 20}$ ( To simplify $420 : 520$ divide it by HCF of $420$ and $520$ HCF of $420$ and $520$ is $20$ )
$420 : 520$ $=$ $\frac{21}{26}$ $=$ $21 : 26$
Hence, the ratio of $420$ and $520$ is $21 : 26$
