Question

- 4/13 + 2 3/26
5/12 + (-2/21)
3/22 × (-1 7/15)
(-1/13):(-3/52)

кто поможет даю 26 баллов :3

Answer 1

- 4/13 + 2 3/26 = -4/13 + 55/26 = -8/26 + 55/26 = 47/26
5/12 + (-2/21) = 5/12 - 2/21 = 35/84 - 8/84 = 27/84
3/22 × (-1 7/15) = 3/22 * (-22/15) = 3/1 * (-1/15) = -1/5
(-1/13):(-3/52)  = -1/13 * (-52/3) = -1 * -4/3 = 4/3
