Solution:
Let the number be x
A number should be added to \frac{7}{12}
12
7
to get\frac{4}{15}
15
4
So, x+\frac{7}{12}=\frac{4}{15}x+
12
7
=
15

−
12
7
Take LCM of 15 and 12 is 60
x=\frac{4}{15}-\frac{7}{12}x=
15
4
−
12

x=\frac{16-35}{60}x=
60
16−35
x=\frac{-19}{60}x=
60
−19
Hence \frac{-19}{60}
60
−19
should be added to \frac{7}{12}
