2.2兀x15÷1%等于几

2.2兀x15÷1% =2.2*3.14*15÷0.01 =2.2*15*3.14÷0.01 =(2+0.2)*15*3.14÷0.01 =(2*15+0.2*15)*3.14÷0.01 =(30+3)*3.14÷0.01 =(30*3.14+3*3.14)÷0.01 =(94.2+9.42)÷0.01 =103.62÷0.01 =10362

解: 15.2×2.8+15.2×2.2 =15.2×(2.8+2.2) =15.2×5 =(15+0.2)×5 =15×5+0.2×5 =75+1 =76

五分之一÷(3分之2+5分之1)x15 =5分之1÷(15x3分之2+15x5分之1) =5分之1÷(10+3) =5分之1÷13 =5分之1x13分之1 =65分之1 朋友,请及时采纳正确答案,下次还可能帮到您哦,您采纳正确答案,您也可以得到财富值,谢谢。

10/21x(21)=(4)÷2/5=(46/3)x15/23=5/8÷(1/16)=10

解:3.4x87+3.4x15-3.4x2 =3.4x(87+15-2) =3.4x100 =340 (6.02+2.8)÷4-2.05 =1.505+0.7-2.05 =2.205-2.05 =0.155

1/3×3.14×(10÷2)×15 =1/3×3.14×5×15 =(1/3×15)×(3.14×5) =5×15.7 =78.5

请采纳

原式 =(30-29)+(28-27)+……+(2-1) =1+1+……+1 =1x15 =15 或者: =(30+2)x15÷2-(29+1)x15÷2 =32x15÷2-30x15÷2 =(32-...

(35+65)x25÷2-20x15÷2 =100×25÷2-20÷2×25 =1250-250 =1000
