Answer:

The unknown number is 2/15.

Step-by-step explanation:

4/5+x=14/15

x=14/15-4/5

x=14/15-12/15

x=2/15

Answer: x = 2/15

Step-by-step explanation:

Let the unknown number be x

4 /5 + x = 14/15

Make x the subject of the equation by subtracting 4/5 from both sides

x = 14/15 - 4/5

The denominator is 15, therefore

x= 14 -12/15 = 2/15

x = 2/15
