Answer 2

1) -1 2/3 × 3.6 = -1 2/3 × 3 6/10 = -5/3 × 36/10 = -180/30 = -6

2) 1 9/31 × (-3.1) = 1 9/31 × (-3 1/10) = 40/31× (-31/10) = -1240/310 = -4

3) -48×(-2 5/12) = -48/1 × (-29/12) = 1392/12 = 116

4) 4.5×(-1 11/15) = 4 5/10 × (-1 11/15) = 45/10 × (- 26/15) = -1170/150 = 7 4/5 = 7 8/10 = 7.8

5) -12 × (-4 23/24) = -12/1 × (-4 23/24) = -12/1×(-119/24) = 1428/24 = 59 1/2 = 59 5/10 = 59.5

6) -7.5×(-2 1/125) = -7 5/10 × (-2 1/125) = -75/10×(-251/125) = 18825/1250 = 15 3/50 = 15 6/100 = 15.06
