42.3+15.9=

*780÷9=
538÷3= 89×47= 20-15.6=538÷3=89×47=20-15.6=

Answer 1

32×26=832

42.3+15.9=58.2

  42.3

(+15.9)/(58.2)

780÷9=86…6
验算：
538÷3=179…1

89×47=4183

20-15.6=4.4

  20

(−15.6)/(4.4)

  42.3

(+15.9)/(58.2)

  42.3

(+15.9)/(58.2)

  42.3

(+15.9)/(58.2)

  42.3

(+15.9)/(58.2)

  42.3  42.3  42.3(+15.9)/(58.2)(+15.9)/(58.2)(+15.9)/(58.2)+15.9+15.9+15.9  58.2  58.2  58.2
780÷9=86…6
验算：
538÷3=179…1

89×47=4183

20-15.6=4.4
