(-2 2/3) : 1,2

2/3 : (-6)

(-0,45) : 1 4/5

(-2,75) : (-2,2)

(-3,5) : (-1 2/5)

Answer 1

-2,1 * (-4 2/7) = 21/10 * 30/7 = 3 * 3 = 9

-7/8 : (-5,6) = 7/8 : 56/10 = 7/8 * 10/56 = 1/8 * 10/8 = 10/64 = 5/32

9/10 : (-3/4) = - 9/10 * 4/3 = - 3/5 * 2 = -6/5

-2 2/3 : 1,2 = -8/3 : 12/10 = -8/3 * 10/12 = -80/36 = -40/18 = -20/9

2/3 : (-6) = -2/3 * 1/6 = -2/18 = -1/9

-0,45 : 1 4/5 = -45/100 : 9/5 = -9/20 * 5/9 = -1/4

-2,75 : (-2,2) = 2 3/4 : 22/10 = 11/4 : 22/10 = 11/4 * 10/22 = 1/2 * 5/2 = 5/4

-3,5 : (-1 2/5) = 3,5 : 7/5 = 35/10 * 5/7 = 7/2 * 5/7 = 5/2 = 2,5
