Write the following in decimals.
$ (a) \frac{3}{4} $
(b) $\frac{2}{5}$
Given :
The given numbers are (i) $\frac{3}{4}$ (ii) $\frac{2}{5}$
To do :
We have to convert the given fractions to decimals.
Solution :
To convert a Fraction to a Decimal, follow these steps:
Step 1: Find a number you can multiply by the bottom of the fraction to make it 10 or a multiple of 10.
Step 2: Multiply both top and bottom by that number.
Step 3: Then write down just the top number, putting the decimal point in the correct spot (one space from the right-hand side for every zero in the bottom number).
(i) $\frac{3}{4}$
$\frac{3}{4} = \frac{(3\times25)}{(4\times 25)}$
$= \frac{75}{100}$
$= 0.75$
(ii) $\frac{2}{5}$
$\frac{2}{5} = \frac{(2\times20)}{(5\times 20)}$
$= \frac{40}{100}$
$= 0.40$
$= 0.4$
Therefore, $\frac{3}{4}$ in decimal is 0.75 and $\frac{2}{5}$ in decimal is 0.4.
