Question

How do you write $0.3$ as a fraction?

Answer 1

Hint:
It’s possible to write decimals in fraction form. To convert a decimal into a fraction, place the decimal number over its place value. For example, in $0.9$, the six is in the tenths place, so we place $9$ over $10$ to create the equivalent fraction, ${\displaystyle \frac{9}{10}}$. If it is needed, we need to simplify the fraction.

Complete Step by Step Solution:
According to the given information, we need to turn $0.3$ to fraction.
Here, the unit place is in ten’s.
 So, $0.3$ is equivalent to ${\displaystyle \frac{3}{10}}$
Properly written as: $0.3={\displaystyle \frac{3}{10}}$

Therefore, $0.3$ can be written as ${\displaystyle \frac{3}{10}}$.

Additional Information:
To turn decimal as a percent, we have to remember that $1$ equals $100\mathrm{\%}$ and for that what we need to do is just to multiply the number by 100 and write $\mathrm{\%}$ symbol against it. To convert this decimal form in percent in the form of $x\mathrm{\%}$, for that we just need to multiply the fraction by $100$.

Note:
In short the relation between percent, decimal and fraction is given by,
$1\mathrm{\%}=0.01={\displaystyle \frac{1}{100}}$.
To turn decimal as a percent, we have to remember that $1$ equals $100\mathrm{\%}$ and for that what we need to do is just to multiply the number by 100 and write $\mathrm{\%}$ symbol against it.
