0.25 3.60.4的简便运算

0.25*3.7*4=1/4*3.7*4=3.7

60x25÷3x4=60÷3*(25*4)=20Ⅹ100=2000

0.25*4*98 =0.25*4*98 =1*98 =98

=8.5

25先乘以4,然后在乘以60,因为25乘以4等于100,所以在乘以60就很好算了.

0.25乘4乘4.7

0.25*13x4=0.25x4x13=1x13=13

0.25*0.975*4=0.25*4*0.975=1*0.975=0.975

(25乘60)乘4=(25*4)*60=100*60=6000

=8.36÷0.25÷4=8.36÷(0.25*4)=8.36÷1=8.36
