Question

how to find the given number is rational
the number to be proven as rational is 0.3178​

Answer 1

Answer:

let the no. be irrational

therefore, it cannot be expressed in p by q form

but, 0.3178 can be expressed in p by q form

= 3178/10000

= 1589/5000

hence, our assumption that 0.3178 Is irrational is wrong since, it is a rational no.
