Answer:
Subtract:
2/3 - 1/2 = 2/3 • 2/2 - 1/2 • 3/3 = 4/6 - 3/6 = 4-3/6 = 1/6
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 the both denominators - LCM(3, 2) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 2 = 6. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - two thirds minus one half = one sixth.
