简便计算为
6.66*2.4+2.22*7.8
=2.22*3*2.4+2.22*7.8
=2.22*(7.2+7.8)
=2.22*(10+5)
=2.22*10+2.22*5
=22.2+11.1
=33.3
所以简便计算后的答案是33.3

原式=6.66x2.4+2.22x3x2.6
=6.66x2.4+6.66x2.6
=6.66x(2.4+2.6)
=6.66x5
=6.66x10÷2
=66.6÷2
=33.3
=6.66x2.4+6.66x2.6
=6.66x(2.4+2.6)
=6.66x5
=6.66x10÷2
=66.6÷2
=33.3

6.66×2.4+2.22×7.8
=2.22×(3×2.4+7.8)
=2.22×3×(2.4+2.6)
=6.66×5
=33.3
=2.22×(3×2.4+7.8)
=2.22×3×(2.4+2.6)
=6.66×5
=33.3
