1. ( 2 2/5 - 3,5 ) : [(-4 1/2) * (-0,4)] = ( 2,4 - 3,5 ) : [(-4,5) * (-0,4)] = -1,1 : 1,8 = -11 : 18 = -11/18
2. ( 1 - 5/7 ) * 0,49 : 0,07 = (7/7 - 5/7) * 49 : 7 = 2/7 * 7 = 2
3. 1,2 * 2/3 - 4,8 : (-2 2/5) = 12/10 * 2/3 - 4,8 : (-2,4) = 24/30 - (-2) = 4/5 + 2 = 2,8
4. (1/2 + 0,7 ) * (0,3 - 3/4) = (0,5 + 0,7) * (0,3 - 0,75) = 1,2 * (-0,45) = - 0,54
5. 4 - (2 1/5 - 3,5 ) * 9/13 = 4 - (2,2 - 3,5) * 9/13 = 4 - (-1,3) * 9/13 = 4 + 13/10 * 9/13 = 4 + 0,9 = 4,9
6. -3 1/2 * (-10) + (-10) *6,5 =-3,5 * (-10) + (-65) = 35 + (-65) = - 30
tyle znalazłam w internecie...
