Question

Express each of the following ratio in the simplest form:
$777:1147$

Answer 1

To convert given ratio $a:b$ to his simplest form, we divide each term by the $HCF$ of $a$ and $b$

$\therefore 777:1147$

$=\frac{777}{1147}$

$=\frac{777÷37}{1147÷37}[\because HCF$ of $777$ and $1147$ is $37]$

$=\frac{21}{31}$

Hence, the simplest form of $777:1147$ is $21:31$
