Question

express 0.31 bar in form p q

Answer 1

Let x = 0.313131......----->>[1]
Periodicity is 2
so multiply by 100 on both sides.
100x = 31.313131.....----->>[2]
Now subtract equation [1] from [2]
100x = 31.313131.....
(-) x = 0.313131....
_______________
99x = 31.0000
__________
now x = 31÷99
i.e. o.31 bar in form of p/q is
31/99
hope it helps

Answer 2

Hello friends!!

Here is your answer :

0.3131

Let x = 0.3131 - - - - - - - (1)

Multiply by 100 on both sides.

100x = 31.3131 - - - - - - (2)

Subtract eqⁿ (1) from eqⁿ (2)

100x - x = 31.3131 - 0.3131

99x = 31

$x = \frac{31}{99}$


$0.3131.. = \frac{31}{99}$



Hope it helps you.. ☺️☺️
