Question

17 3/4 + 5 5/6 = ,
3 5/6 - 1 1/2 =,
-2 1/3 + 1 3/4 =,
1 1/8 * (-1 4/6) =,
(-1 5/15): (-16/25) =,

Answer 1

17 3/4 + 5 5/6 = 17 9/12 + 5 10/12 = 23 7/12

3 5/6 - 1 1/2 = 3 5/6 - 1 3/6 = 5 2/6 = 5 1/3

-2 1/3 + 1 3/4= -(2 1/3 - 1 3/4) = -(2 4/12 - 1 9/12) = -7/12

1 1/8 * (-1 4/6) = 9/8 * (-10/6) =  3/4 * (-5/2) = -15/8= -1 14/15

(- 1 5/15) : (-16/25) = -20/15 : (-16/25) = -20/15 * (- 25/16) = -5/3 * (-4/4) = 20/12=  1 8/12

Mam nadzieje że pomogłem i wsztko powinno być dobrze :D
