(1)0.24+9.8+0.72
=9.8+(0.24+0.72)
=9.8+0.96
=10.76
(2)10-2.55-7.45
=10-(2.55+7.45)
=10-10
=0
(3)48.3-27.8+51.8
=48.3+(51.8-27.8)
=48.3+24
=72.3
(4)
80.96+3.65+6.35
=80.96+(3.65+6.35)
=80.96+10
=90.96
=9.8+(0.24+0.72)
=9.8+0.96
=10.76
(2)10-2.55-7.45
=10-(2.55+7.45)
=10-10
=0
(3)48.3-27.8+51.8
=48.3+(51.8-27.8)
=48.3+24
=72.3
(4)
80.96+3.65+6.35
=80.96+(3.65+6.35)
=80.96+10
=90.96
