(3/4+1/5)%(5/6%1/2)=?(用脱式计算)

4/5+8*45% =0.8+8x0.45 =0.8+3.4 =5.2 3.3÷2又1/5*5% =3.3÷11/5x0.05 =1.5x0.05 =0.75 8.8*(1+25%) =1.1x8x1.25 =1.1x10 =11 (5/13-0.8)÷(60%-6%) =(25/65-52/65)÷27/50 =-27/65÷27/50 =-10/13

1、原式=0.8+8*0.45=0.8+3.6=4.4 2、原式=3.3÷2.2*0.05=1.5*0.05=0.075 3、原式=8.8*1.25=11 4、原式=(5/13-4/5)÷54%=(25/65-52/65)÷0.54=-27/65÷0.54=-50/65=-5/13

一、红色 7/45+0/45+3/66+6/11+12%=3份+1份+2克+3克+1没做到那么艳 二、黄色:8/33+0/33+0/88+3/66+12%=3份+1份+3克+3克+1 三、橙黄:8/33+8/43+0/45+/3/66+12%=8份+1份+5克+1克+1 8/33+0/45+/3/66+12%=20份+1份+2克:1 四、紫色6/45+0/45+3/66+...
