"99.99×11.11+33.33×667"用简便运算怎么计算?

82×11+33×06=82x11+(3x6)x11=82x11+18x11=(82+18)x11=100x11=1100

原式 =66.66x11.11+33.33x77.78 =33.33x2x11.11+33.33x77.78 =33.33x22.22+33.33x77.78 =33.33x(22.22+77.78) =33.33x100 =3333

11×11=4 即;(1+1)x(1+1)=4 22+22=16 即;(2+2)x(2+2)=16 33+33=36 即;(3+3)x(3+3)=36 ...... 所以 (9+9)x(9+9)=18x18=324 99×99=324 希望能帮助到你

99×11+67×3 =33×3×11+67×33 =33×33+67×33 =33×(33+67) =33×100 =3300

先提出11分之8 等于11分之8乘以(13分之4加26分之3),等于11分之8乘26分之11等于13分之4

原式等于 11×(52+48) =11×100 =1100 所以原式的计算结果为1100.

原式=3*11+7*11+66*11 =76*11=836 望采纳

=11×(166+33+1) =11×200 =2200

50×11+48×33+6×11 =50×11+48×3×11+6×11 =50×11+144×11+6×11 =(50+144+6)×11 =200×11 =2200
