Answer:

25=10+\frac{1}{3}n.

Step-by-step explanation:

It is given that the sum of 10 and one-third of a number  is 25.

Let as consider n be the unknown number.

One-third of a number =\frac{1}{3}n

Sum of 10 and one-third of a number =10+\frac{1}{3}n

The sum of 10 and one-third of a number  is 25. It can be written as

25=10+\frac{1}{3}n
