如图

7.5*(10+0.1)-0.75=7.5*10-7.5*0.1-0.75=75

=7.5x(3.8+6.2)=7.5x10=75

原式=2.7*7.5+7.2*7.5+0.1*7.5=(2.7+7.2+0.1)*7.5=10*7.5=75

0.75x56+3/4x56-13x75% =0.75x56+0.75x56-13x0.75 =0.75x(56+56-13) =0.75x99 =0.75x100-0.75 =75-0.75 =74.25

5.7*7.5-0.75*37简便计算 =5.7x7.5-7.5x3.7 =7.5x(5.7-3.7) =7.5x2 =15

42.5×2.5+425×0.75 =42.5×2.5+42.5×7.5 =42.5×(2.5+7.5) =42.5×10 =425

0.75+7.5*0.9 =7.5X0.1+7.5X0.9 =7.5X(0.1+0.9) =7.5X1 =7.5

0.75×13+7.5×8.7 =0.75×13+0.75×87 =0.75×(13+87) =0.75×100 =75
