75+8.95+10.25 6.38-1.8+3.62
95÷1.25÷0.8 9.4×5-10.6.
7×9.9+0.1×0.7 13.8+15.6÷0.4.
85×1.25+0.85×1.75 2.15×0.9+21.5×0.11.
(1)75+8.95+10.25
=75+(8.95+10.25)
=75+19.2
=94.2
(2)6.38-1.8+3.62
=(6.38+3.62)-1.8
=10-1.8
=8.2
(3)95÷1.25÷0.8
=95÷(1.25×0.8)
=95÷1
=95
(4)9.4×5-10.6
=47-10.6
=36.4
(5)7×9.9+0.1×0.7
=7×9.9+0.01×7
=7×(9.9+0.01)
=7×9.91
=7×(10-0.09)
=7×10-7×0.09
=70-0.63
=69.37
(6)13.8+15.6÷0.4
=13.8+39
=52.8
(7)85×1.25+0.85×1.75
=106.25+1.4875
=107.7375
(8)2.15×0.9+21.5×0.11
=2.15×0.9+2.15×1.1
=2.15×(0.9+1.1)
=2.15×2
=4.3
