4.6 0.25 6.4 4简便计算

5.14÷0.25+4.6*4 =5.14÷1/4+4.6*4 =5.14*4+4.6*4 =(5.14+4.6)*4 =9.74*4 =? (似乎你题目中的4.6有误)

4.6/0.25=4.6*4 因为0.25=1/4.所以4.6/0.25=4.6/(1/4)=4.6*4.

4.6乘0.25的简便运算,4.6x0.25=(4+0.6)x0.25=4x0.25+0.6x0.25=1+0.15=1.15希望能帮到你

4.6/(0.25*0.23)简便计算 解:原式=46/(0.25x2.3)=2/(0.25x1)=2/(1/4)=2x4=8

0.25*6.4=0.25*4*1.6=1*1.6=1.6

4.6*0.25+5.4÷4=4.6*0.25+5.4*1/4=4.6*0.25+5.4*0.25=(4.6+5.4)*0.25=10*0.25=2.5

4.6÷4÷0.25=4.6*1/4÷(1/4)=4.6*1/4*4=4.6

25*9 =25x(100-1) =25x100-25 =2500-25 =2475 (25+60)*4 =25x4+60x4 =100+240 =340

(0.25x0.4)x4.6=0.1x4.6=0.46

6.4/0.25=6.4÷1/4=6.4*4=(6+0.4)*4=6*4+0.4*4=24+1.6=25.6
