Answer:

Step-by-step explanation:

Let the number = x.

We are trying to find out what number (x) we would need to add to 7/12 to get 4/15

[tex]\frac{7}{12} + x = \frac{4}{15}[/tex]

Subtract 7/12 from both sides.

[tex]x = \frac{4}{15} - \frac{7}{12}[/tex]

We need to make the denominators of the fractions the same.

[tex]\frac{4}{15} = \frac{16}{60}[/tex]

[tex]\frac{7}{12} = \frac{35}{60}[/tex]

So,

[tex]x = \frac{16}{60} - \frac{35}{60} = - \frac{19}{60}[/tex]
