Question
Write the following ratios in the simplest form: $Rs. 6.30 : Rs. 16.80$
✓
Answer
The given ratio $= Rs. 6.30 : Rs. 16.80$
$=\frac{\text{Rs. }6.30}{\text{Rs. }16.80}$
$=\frac{630}{1680}$ To express it in simplest form,
we divide the numerator and denominator by the $HCF$ of $630$ and $1680$.
Now, $HCF$ of $630$ and $1680 = 210$
$\therefore\frac{630}{1680}=\frac{630\div210}{1680\div210}=\frac{3}{8}$
$\therefore\text{Required ratio}= 3:8$
$=\frac{\text{Rs. }6.30}{\text{Rs. }16.80}$
$=\frac{630}{1680}$ To express it in simplest form,
we divide the numerator and denominator by the $HCF$ of $630$ and $1680$.
Now, $HCF$ of $630$ and $1680 = 210$
$\therefore\frac{630}{1680}=\frac{630\div210}{1680\div210}=\frac{3}{8}$
$\therefore\text{Required ratio}= 3:8$
