Solution:
3/7 - 6/11 - 8/21 + 5/22
Find the least common multiples of the denominator 7, 11, 21 and 22.
7, 11, 21, 22 = 462
Then multiply so that they have same denominator
462[3/7 - 6/11 - 8/21 + 5/22] 462
462/7 * 3 = 198
462/11 * 6 = 252
462/21 * 8 = 176
462/22 * 5 = 105
198 - 252 - 176 + 105 = -125/462
Hope this would help
