解比例:乄:3/8=6:1/4,0.4/4.8=乄/24,(1/3+1/4...

5.5×2=119.6÷4.8=23-1.5×2=02×3.1=6.22.4×0.5=1.20.125×8-0.1=0.90.48÷6=0.086.4-4=2.40.6÷3+3=3.20.91÷13=0.073.25+0.75=49.9-0.9÷0.1=0.917×40=680 100-63=37 3.2+1.68=4.884.8÷8=0.60.5+0.5÷0.5=1.550×0.8=400.99÷33=0.034×7.5×2.5=754.5×0.1...

3、 2/25、 6、 3/8 你几年级啊 这东西我口算都算出来了

0.5+0.4=0.9; 1.8-0.7=1.1; 3.4-0.4=3; 0.9+1.6=2.5; 4.8+1.2=6; 14.5-4.5=10; 1-0.89=0.11 26.9-16.9=10; 5.8+2=7.8; 6.74-6.4=0.34; 4.3-1.6=2.7; 5-0.2=4.8; 7.5+2.5=10; 2-0.8=1.2.

5又1/5-[2又1/6+(-4.8)-(-四又5/6)] =5又1/5+4.8-2又1/6-四又5/6 =10-7 =3.

(4/9)的1/2次方=2/3 (-4.8)的0次方=0 (3*3/8)的-1/3次方=3√(8/9)=2/(3√9)(这个估计数字有问题) (0.1)的-2次方=100 剩下的自己去算吧

6000-100-1+10000-4 8753-1000-3 25+14+(0.07+0.03+0.95) 0.125*8*54/7 22×1/5×1/3×1/4+3×1/8×1/5×1/4 2.1×1/20-4.8×1/30

4.5+0.76=5.26; 1-0.01=0.99; 0.54-0.5=0.04; 6.5-5.6=0.9; 10-4.28=5.72; 4.8+2=6.8; 0.24+0.6=0.84; 1.7+0.3=2; 37.8-16.4-13.6=7.8; 1.8+0.2-1.8+0.2=0.4.故答案为:5.26、0.99、0.04、0.9、5.72、6.8、0.84、2、7.8、0.4.

(0.1+4.9)+(0.2+4.8)+……(2.4+2.6)+2.5=5×24+2.5=122.5

解:只要变成乘法,即两内项相乘=两外项相乘 0.8:x=1.2:4,1.2x=3.2, x=8/3≈2.67. 10:x=5:3分之4, 5x=10*4/3 , x=8/3≈2.67, 3分之x=24分之4.8, x=4.8/8=0.6, 1.8:5.4=X:5.7, 5.4x=1.8*5.7, x=5.7/3=1.9, 25:0.4=75:x, 25x=75*0.4, x=1.2, 2...

0.16,6.7,11,0.99,7.12,0.19,0.65,0.67,70,0.84。
