Answer 1

Answer:

\frac{-19}{60}

Step-by-step explanation:

To Find :What number should be added to \frac{7}{12} to get\frac{4}{15}?

Solution:

Let the number be x

A number should be added to \frac{7}{12} to get\frac{4}{15}

So, x+\frac{7}{12}=\frac{4}{15}

x=\frac{4}{15}-\frac{7}{12}

Take LCM of 15 and 12 is 60

x=\frac{4}{15}-\frac{7}{12}

x=\frac{16-35}{60}

x=\frac{-19}{60}

Hence \frac{-19}{60} should be added to \frac{7}{12} to get\frac{4}{15}
