Question
Express the following without using decimals: $3.5\ cm$
✓
Answer
We know that $10\ mm = 1\ cm.$
So, $1\text{mm}=\frac{1}{10}\text{cm}$
Therefore, $3.5 = 3 + 0.5$
$=3+\frac{5}{10} = 3\ cm$ and $5 \ mm$
So, $1\text{mm}=\frac{1}{10}\text{cm}$
Therefore, $3.5 = 3 + 0.5$
$=3+\frac{5}{10} = 3\ cm$ and $5 \ mm$
