Question

if you multiply a number by 2 and add 1/3. the result is 25/21 . find the numbers​

Answer 1

Answer:

the number will be 1/3

Step-by-step explanation:

Let the number be x :

then,

ATQ:

2x + 1/3 = 25/21

2x = 25/21 - 1/3

or, 2x = 14/21

or, x = 14/42

or, x = 1/3

Answer 2

Given that :-

After multiplying $2$ and adding $\frac{1}{3}$, the result is = $\frac{25}{21}$

_________________________________

To find :-

∴ The number, which after multiplying $2$ and adding $\frac{1}{3}$ is $\frac{25}{21}$.

_________________________________

Required :-

⇒ $x$ × $2 + \frac{1}{3} = \frac{25}{21}$

⇒ $2x + \frac{1}{3} = \frac{25}{21}$

⇒ $\frac{25}{21} - \frac{1}{3}$

⇒ $\frac{25}{21} - \frac{7}{21} = \frac{18}{21} = \frac{6}{7}$

⇒ $2x =\frac{6}{7}$

⇒ $1x = \frac{3}{7}$

_________________________________

To check :-

⇒ $\frac{3}{7}$ × $2 + \frac{1}{3} = \frac{25}{21}$

⇒ $\frac{6}{7} + \frac{1}{3}$

⇒ $\frac{25}{21} = 1\frac{4}{21}$
