Question

What should be added to 53/7 to get 12?

Answer 1

12 -53/7 is your answer

Answer 2

Answer: The result is $\dfrac{31}{7}$.

Step-by-step explanation:  Let the value of the number which is to be added to $\dfrac{53}{7}$ to get $12$ be $x$.

Now, we will try to make an algebraic equation involving the unknown variable $x$, and then we will try to solve the equation and find the value of $x$.

From the given information, we can write

$\dfrac{53}{7}+x=12\\\\\Rightarrow x=12-\dfrac{53}{7}\\\\\Rightarrow x=\dfrac{84-53}{7}\\\\\Rightarrow x=\dfrac{31}{7}.$

Thus, the number to be added is $\dfrac{31}{7}$.
