Question

What should be added twice the rational number -7/3to get 3/7

Answer 1

The number $\bold{\frac{113}{35}}$ should be added to get $\bold{\frac{3}{7}}$.

Solution:

Now let us take the number that, should be added as X

The question says that X, should be added, to twice the rational number that is $-\frac{7}{3}$ to get $\frac{3}{7}.$

Now let us multiply 2 to $-\frac{7}{3}$  we get the value $-\frac{14}{3}.$

Now adding X to $-\frac{14}{3}$and equating it with $\frac{3}{7}$we get,m  

$-\frac{14}{5}+\mathrm{X}=\frac{3}{7}$

$X=\frac{113}{35}$

The value of X form after solving the equation is $\frac{113}{35}$

Therefore, the number $\frac{113}{35}$ should be added to get \$frac{3}{7}$.
