Answer 2

The value of 2.12 bar in p/q form is 210/99

Given:

A non-terminating decimal number is given 2.12 bar.

To Find:

we need to find the value of the given number in p/q form.

Solution:

Let

$x = 2.12121212.........$

Multiplying by 100 on both sides we get

$100x = 212.12121212.......$

Now subtract these two equations. We get

$99x = 210$

$x = \frac{210}{99}$

Therefore, the p/q form is 210/99.
