Question
Find the ratio of: $90\ cm$ to $1.05m$
✓
Answer
$90\ cm : 1.0m$ (or) $90\ cm : 105\ cm (1m = 100\ cm)$
$\frac{90}{105}=\frac{90\div15}{105\div15}=\frac{6}{7}$
$(H.C.F$ of $90$ and $105$ is $15.)$
$\therefore 6 :7 $
$\frac{90}{105}=\frac{90\div15}{105\div15}=\frac{6}{7}$
$(H.C.F$ of $90$ and $105$ is $15.)$
$\therefore 6 :7 $
