Answer: 7/4 and  1 3/4

Step-by-step explanation:

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(4, 4) = 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 4 = 16. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - seventeen quarters minus ten quarters = seven quarters.
