Question

7) How much must be added to 2 times of 5/7 to get 3. Let us calculate.
​

Answer 1

Answer: 11 / 7

Step-by-step explanation:

Let the no. be x

Given,

(2×5/7) + x = 3

10/7 + x = 3

x = 3 - 10/7

= (21 - 10)/ 7

= 11/7

Thus, 11/7 should be added

Answer 2

The value of x should be $\frac{11}{7}$.

Step-by-step explanation:

Consider the provided information.

We need to determine the value which must be added to 2 times of 5/7 to get 3.

Let the number is x.

Now translate the provided statement.

$2\times\frac{5}{7}+x=3$

$\frac{10}{7}+x=3$

$x=3-\frac{10}{7}$

$x=\frac{21-10}{7}$

$x=\frac{11}{7}$

Hence, the value of x should be $\frac{11}{7}$.
