Question

(2,5-2 1/3)*(-5 1/7)+1 1/3:(-5,6)

Answer 1

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

1/6*(-5 1/7)=1/6*(-36/7)=-6/7

1 1/3:(-5,6)=4/3*(-5/28)=-15/7=-2 1/7

-6/7+(-2 1/7)=-6/7-2 1/7=-3

Answer 2

1) 2.5 - 2 1/3=11/6=1 5/6

2) 1 5/6 * (-5 1/7)=11/6*(- 36/7)=-66/7=-9 3/7

3) 11/3:(-5,6)=-55/84

4) - 9 3/7+(-55/84)= -379/84=-4 43/84
