Answer 2

1) 1/6 - 1/9 = (3/18) - (2/18) = 1/18 2) 8/10 - 6/15 = (12/15) - (8/15) = 4/15 3) 5/12 - 4/15 = (25/60) - (16/60) = 9/60 = 3/20 4) 5 целых 3/4 - 3 целых 5/18 = (20/4) + (3/4) - (17/18) = 23/4 - 17/18 To subtract fractions with different denominators, we need to find a common denominator. The least common multiple of 4 and 18 is 36. = (23/4)(9/9) - (17/18)(2/2) = (207/36) - (34/36) = 173/36 5) 2/26 - 1/39 = (3/78) - (2/78) = 1/78 6) 8 целых 7/34 - 7 целых 5/517 = (8 * 34 + 7/34) - (7 * 517 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517) = (272 + 7/34) - (3619 + 5/517
