Question

If 0.142857142857…… express in form of m/n, then the value of 2 (m+n) is

Answer 1

Step-by-step explanation:

Let

x= 0.142857...... Equation 1

x × 1000000= 0.142857.....× 1000000

1000000x=142857.142857 Equation 2

Now, Equation 2-1

.: 1000000x-x= 142857.142857-0.142857

999999x=142857

x=142857/999999

Answer 2

Answer:

Required value is 2.28571429e12 Where e = 2.71828183

Step-by-step explanation:

Here given number is 0.142857142857.

Here we want to convert this number in $\frac{m}{n}$form.

This is a problem of fraction.

Here n is denominator and m is numerator.

For this first we need to remove decimal from 0.142857142857.

Now,

$0.142857142857 = \frac{142857142857}{1000000000000}$

So we can say

$m = 142857142857 \\ n = 1000000000000$

Now question is what is the value of 2(m+n)?

Therefore,

$2(m + n) = 2(142857142857 + 1000000000000) = 2(1142857142857)$

$= 2.28571429e12$

Where e = 2.71828183
