Given
5 (3/7) First convert the given mixed fraction into improper fraction we get
(38/7)
Let x be the number added to (38/7) to get 12
Therefore
x + (38/7) = 12
x = 12 – (38/7)
By taking LCM for 7 and 1 is
7 x = (12 × 7 – 38)/7
x = (84 – 38)/7
x = (46/7)
Hence (46/7) is the number which is added to 5 (3/7) to get 12.
