Question

what should be added to 1/2+1/3+1/5 to get 3​

Answer 1

Answer:

let the no. be x

1/2+1/3+1/5+x=3

$\frac{1}{2} + \frac{1}{3} + \frac{1}{5} + x = 3 \\ \frac{15}{30} + \frac{10}{30} + \frac{6}{30} + x = 3 \\ \frac{31}{30} + x = 3 \\ x = 3 - \frac{31}{30} \\ x = \frac{ 90- 31}{30} \\ x = \frac{59}{30}$
