Question

what should be added to 1/3 to get 5/8​

Answer 1

Let the number be x.

$x + \frac{1}{3} = \frac{5}{8} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = \frac{5}{8} - \frac{1}{3} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = \frac{15 - 8}{24} \\ \: \: \: \: \: \: \: \: \: \: x = \frac{7}{24}$

Therefore,7/24 is added to 1/3 to get 5/8...
