Question

What should we added -7/3 to get 3/7

Answer 1

Answer:

58/21

Step-by-step explanation:

make the unknown value as x use transposing method and find the value of x

Answer 2

$\textrm{Let the unknown number be x}$\\

Given equation :-\\\\

$\boxed{\fbox{\frac{-7}{3}+x=\frac{3}{7}}}$\\\\

$\textrm{Now , we need to solve this equation}$\\\\

$\textrm{Taking\frac{-7}{3}on right hand side it becomes:}$\\\\

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

$\textrm{then we need to take the LCM of the denominators 7 and 3}$\\\\

$\bf\large\begin{array}{r|l}7&7,3\\\cline{2-2}3&1,3 \\ \cline{2 - 2}&1,1 \end{array}$\\\\

$\frac{3}{7}\times\frac{3}{3}=\frac{9}{21}$\\

$\frac{-7}{3}\times\frac{7}{7}=\frac{-49}{21}$\\\\

$\implies\:\frac{9-(-49)}{21}$\\

$\implies\:\frac{9+49}{21}$\\

$\implies\:\frac{58}{21}$\\
