Explanation:
One method for converting a fraction to a decimal is to change the denominator to a power of 10, such as 10, 100, 1000, or 10,000.
For some fractions this is possible such as with denominators of: 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, etc... Noticeably absent from this list are numbers which are prime numbers or multiples of 3, 7 etc.
Top and bottom should be multiplied by the same number to obtain an equivalent fraction. This is equivalent to multiplying by 1, which has no effect on a number's value.
$\frac{8×4}{25×4}=\frac{32}{100}=0.32⇒\left(\frac{4}{4}=1\right)$
If the denominator cannot be changed into a power of 10, then you have to divide the numerator by the denominator.
$\frac{3}{7}=3÷7=0.4285714285\dots .$ This is a recurring decimal.
It can be shown as $\stackrel{―}{0.428571}$ or rounded off to a suitable level of accuracy.$\frac{3}{7}\approx 0.429$
