快！！

Answer 1

0.56×3.68+6.32×0.56
=0.56(3.68+6.32)
=0.56X10
=5.6

7.8×10.1
=7.8(10+0.1)
=78.78

Answer 2

0.56×3.68+6.32×0.56
=0.56*（3.68+6.32）
=0.56*10
=5.6

7.8×10.1
=7.8（10+0.1）
=78+0.78
=78.78

Answer 3

0.56×3.68+6.32×0.56
=0.56*(3.68+6.32)
=0.56*10
=5.6
7.8*10.1
=7.8*(10+0.1)
=78+0.78
=78.78

Answer 4

0.56×(3.68+6.32)＝5.6
7.8×（10＋0.1）＝78＋0.78＝78.78
