Question

Convert the decimal into fractions.

$3.5$

Answer 1

Method 1:

We know that $3.5$can be written as $3+\frac{5}{10}$ $($ $3$ ones and $5$ tenths $)$

$\Rightarrow 3+\frac{5}{10}$ $=$$\frac{3\times 10+5\times 1}{10}$ $($LCM of $1$ and $10$ is $10$ $)$

$=$$\frac{35}{10}$

Therefore, $3.5$ in the fraction form is $\frac{35}{10}$

Alternate Method:

Step 1: Write the number without a decimal point in the numerator.

$\Rightarrow \frac{35}{}$

Step 2: In the denominator, write $1$ followed by as many zeroes as the number of digits after the decimal point in the denominator.

$\Rightarrow \frac{35}{10}$

Therefore, $3.5$ in the fraction form is $\frac{35}{10}$.
