Answer 2

Answer:

The decimal expansion of the rational number will terminate after 4 decimal places.

Given: 14587/1250

=\frac{14587}{2 \times 5^{4}}=

2×5

4

14587

Add 2^{3}2

3

to both numerator and denominator

$$\begin{lgathered}\begin{array}{l}{=\frac{14587 \times 2^{3}}{2^{4} \times 5^{4}}} \\ {=\frac{14587 \times 8}{(2 \times 5)^{4}}}\end{array}\end{lgathered}$$

Now simplify the above step by simple mathematical calculations

= 116696/10000

=11.6696

Hence here in the given problem the decimal places will terminate after 4 decimal places or decimal fractions.

So from this we can conclude that the rational numbers can be expressed in the form of decimal fractions also.
