# Write Down the Decimal Expansions of the Following Rational Numbers by Writing Their Denominators in the Form 2m × 5n, Where, M, N Are Non-negative Integers. 14588 625 - Mathematics

Numerical

Write down the decimal expansions of the following rational numbers by writing their denominators in the form 2m × 5n, where, mn are non-negative integers.$\frac{14588}{625}$

#### Solution

The given number is $\frac{14588}{625}$ Clearly, 625 = 54 is of the form 2m × 5n, where m = 0 and n = 4.

So, the given number has terminating decimal expansion.

$\therefore \frac{14588}{625} = \frac{14588 \times 2^4}{2^4 \times 5^4} = \frac{14588 \times 16}{\left( 2 \times 5 \right)^4} = \frac{233408}{\left( 10 \right)^4} = \frac{233408}{10000} = 23 . 3408$

Is there an error in this question or solution?
