用简便方法计算.10.1×7.5%0.75怎样算简便

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

7.5×32+0.75×320的简便计算 =7.5x(32+32) =7.5x8x8 =60x8 =480

题目漏了些什么,如果就是这样没有简便方法

0.75×13+7.5×8.7 =0.75×10×1.3+7.5×8.7 =7-5×1.3+7.5×8.7 =7.5×(1.3+8.7) =7.5×10 =75

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

7.5╳0.43+0.75╳4.3用简便方法计算 =0.43×(7.5+7.5) =0.43×15 =6.45

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

(0.75+7.125-7.5)*8简便方法计算 =0.75x8+7.125x8-7.5x8 =6+57-60 =3

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

7.5×1.36÷0.75 =7.5÷0.75x1.36 =10x1.36 =13.6 , 你好,本题已解答,如果满意 请点右下角“采纳答案”。
