8.65减3.7加1.35减6.3怎样简算?谢谢
8.65+1.35-3.7-6.3=10-(3.7+6.3)=10-10=0
脱式计算,能简算的要简算(1)8.65-3.7+1.35-6.3 (2)[2.1+3.61÷(7...
(1)8.65-3.7+1.35-6.3
=(8.65+1.35)-(3.7+6.3),
=10-10,
=0;
(2)[2.1+3.61÷(7.2-5.3)]×30
=[2.1+3.61÷1.9]×30,
=[2.1+1.9]×30,
=4×30,
=120;
(3)1.2+36÷[1.44×(0.1-0.05)]
=1.2+36÷[1.44×0.05],
=1.2+36÷0.072,
=1.2+500,
=501.2;
(4)(16.5×3+3×7.5)÷6
=[(16.5+7.5)×3]÷6,
=24×3÷6,
=72÷6,
=12.
8.65-3.7+1.35-6.3
原式=(8.65+1.35)-(3.7+6.3)=10-10=0
25.6加1.35减25.6加8.65简便计算
=25.6-25.6+1.35+8.65
=1.35+8.65
=10
100减9.9乘(8.75减8.65)简算
原式
=100-9.9x(8.75-8.65)
=100-9.9x0.1
=100-0.99
=99.01
供参考。
简算72.8除以0.91减8.65怎么简算
72.8÷0.91-8.65
=80-8.65
=71.35
没有简算,直接计算即可
13.52-3.7 6.48-6.3怎样简算?
13.52-3.7+ 6.48-6.3
=13.52+6.48-(3.7+6.3)
=20-10
=10
3.79-1.35+17.28-8.65=?要简算
3.79-1.35+17.28-8.65
=3.79+17.28-1.35-8.65
=3.79+17.28-(1.35+8.65)
=21.07-10
=11.07
147.5减(6.3加47.5)能简算吗
147.5-(6.3+47.5)
=147.5-6.3-47.5
=147.5-47.5-6.3
=100-6.3
=93.7
8.65-8.65×0.24+0.76怎样简算
=8.65*(1-0.24)+0.76
=8.65*0.76+0.76
=8.65*(1+0.76)
=8.65*1.76
=15.224
