Question

1.2x33.2+4.8x16.7简便运算？

Answer 1

原式=1.2×33.2＋1.2×4×16.7=1.2×（33.2+4×16.7）=1.2×100=120

Answer 2

=1.2X（33.2+4X16.7）=1.2X4X（8.3+16.7）=1.2X4X25=120

Answer 3

原式=1.2（33.2+4x16.7)=1.2（33.2+66.8）=1.2x100=120

Answer 4

1.2×33.2＋4.8×16.7
＝1.2×33.2＋1.2×66.8
＝1.2×(33.2＋66.8)
＝1.2×100
＝120

Answer 5

1.2×33.2＋4.8×16.7
＝1.2×（33.2＋66.8）
＝1.2×100
＝120
