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(10, 4) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 4 = 40. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - thirty-three tenths minus seven quarters = thirty-one twentieths.
