Answer:

15/25 - 2/5 = 0.2

Step-by-step explanation:

Subtract: 15/

25

- 2/

5

= 15/

25

- 2 · 5/

5 · 5

= 15/

25

- 10/

25

= 15 - 10/

25

= 5/

25

= 5 · 1/

5 · 5

= 1/

5

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(25, 5) = 25. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 25 × 5 = 125. In the following intermediate step, cancel by a common factor of 5 gives 1/

5.
