Answer:
2 2/7
Step-by-step explanation:
Subtract: 5/ 7 - 9/ 3 = 5 · 3/ 7 · 3 - 9 · 7/ 3 · 7 = 15/ 21 - 63/ 21 = 15 - 63/ 21 = -48/ 21 = 3 · -16/ 3 · 7 -16/ 7
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(7, 3) = 21. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 7 × 3 = 21. In the following intermediate step, the fraction result cannot be further simplified by canceling.
