Question

what number should be added to 5 / 14 to get 12/7​

Answer 1

Answer:

19/14 is the answer.

Step-by-step explanation:

Let the number added be x

$\frac{5}{14} +x = \frac{12}{7} \\ = > x = \frac{12}{7} - \frac{5}{14}$

Now, by taking LCM of 7 and 14 i.e 14.

$= > x = \frac{2(12) - 5}{14} \\ = > x = \frac{24 - 5}{14} \\ x = > \frac{19}{14}$

Hence, the number added should be 19/14.
