13.25+35+6.75简算怎么算? 13.25+35+6.75简算怎么算?13.25+35+6.75=13 + 0.25 + 35 + 6 + 0.75= 13+35+6 + 0.25+0.75
13.25+35+6.75简算怎么算?
13.25+35+6.75简算怎么算?
13.25+35+6.75
=13 + 0.25 + 35 + 6 + 0.75
= 13+35+6 + (0.25+0.75)
=13+35+6+1
=(13+6+1) + 35
=20+35
=55
8.25-(7.28-6.75)脱式计算能简算吗?能简算的话怎么简算?
=8.25+6.75—7.28
=15—7.28
=7.72
简算:6.75+6.75*7.6+1.4*6.75
6.75+6.75×7.6+1.4×6.75=6.75×1+6.75×7.6+1.4×6.75=6.75×(1+7.6+1.4) =6.75×10=67.5
12一4.25一6.75怎么简算
12一4.25一6.75
=12-(4.25+6.75)
=12-11

计算,能简算的要简算(1)13.25-5.07-2.93 (2)42.8...
(1)13.25-5.07-2.93
=13.25-(5.07+2.93)
=13.25-8
=5.25
(2)42.8×7.8+7.8×57.2
=7.8×(42.8+57.2)
=7.8×100
=780
(3)1.5×2.7-30÷25
=4.05-1.2
=2.85
(4)[17.5-(4.9+2.1)]×2.3
=[17.5-7]×2.3
=10.5×2.3
=24.15

6.75*(0.9 0.7)简算
6.75*(0.9-0.7)
=6.75*0.2
6.75*2/10
=1.35
简算:75.8-3.25-6.75
=75.8-(3.25+6.75)
=75.8-10
=65.8
15.9 (6.75-5.89)简算
15.9 +(6.75-5.89)
=15.9+0.86
=16.76
