Question

Give full answer of my question express no 0.3178 in form of rational no

Answer 1

0.3178
= 3178/10000
 Since the decimal point is after 4 digits on the left side, we will add 4 zeros to the denominator.

I hope there is no bar on the number but if there is one then we will solve it in the following way:-

x= 0.317831783178....                 (1)
10000x= 3178.31783178...          (2)
 
Subtracting (1) from (2)
10000x-x = 3178.3178...-0.3178...
9999x= 3178
Solving for 'x',
x= 3178/9999

Answer 2

3178/10000 is the answer ok
