Question

Express 0.25ˉ0.\bar{25} in the form pq\frac{p}{q}​, where p and q are integers and q0q \neq 0​.

A.

2510000\frac{25}{10000}​​

B.

2590\frac{25}{90}​​

C.

25100\frac{25}{100}​​

D.

2599\frac{25}{99}​​

Correct option is D

Given:

The repeating decimal is:

0.\overline{25}

Solution:

Let x = 0.250.\overline{25}​​

Multiply both sides by 100 (since the repeating part has 2 digits):

100x = 25.2525.\overline{25}​​

Subtract the original equation (x=0.25x = 0.\overline{25}​) from this:

100x - x = 25.250.2525.\overline{25} - 0.\overline{25}​​

99x = 25

x = 2599 \frac{25}{99}​​

The value of 0.250.\overline{25}​ in the form of pq \frac{p}{q}​ is: 2599\frac{25}{99}​​
