(-98)×(-0.125)+98×1/8×(-4/7)

=98×1/8×(1-4/7)

=98×1/8×3/7

=21/4

63×(-1又九分之一)+(-18)/(-0.9)

=63×(-10/9)+(-18)/(-9/10)

=10/9×(18-63)

= - 50

|3-4|+3又二分之一 ÷ (-1又四分之三) - (-1/3) ×3

=1-7/2×4/7+1

=0

2又4/5 × (-4/7) +8.75 ×(-4/7) +1.2×(-4/7) - 2又3/4 × (-4/7)

=(-4/7)× (14/5+35/4+6/5-11/4)

=-40/7

-2/3+(-1/6)-(-1/4)-1/2

=-4/6-1/6+1/4-2/4

=-13/12

-5/3×(0.5-2/3)÷ 10/9

=5/3×1/6×9/10

=1/4

42×(-2/3)+(-3/4)÷(-0.25)

= - 28+(3/4)×4

= - 25

(-56)÷(-12+8)+(-2)×5

=14-10

=4
