Answer 3

7/13×5/11+5/13×4/11巧算的结果等于5/13。 解:7/13×5/11+5/13×4/11 =(7x5)/(13x11)+(5x4)/(13x11) =5/13x7/11+5/13x4/11 =5/13x(7/11+4/11) =5/13x(7+4)/11 =5/13x11/11 =5/13

Answer 4

7/13×5/11+5/13×4/11
=(7x5)/(13x11)+(5x4)/(13x11) =5/13x7/11+5/13x4/11 =5/13x(7/11+4/11) =5/13x(7+4)/11
=5/13x11/11
=5/13

Answer 5

7/13×5/11+5/13×4/11
=(7x5)/(13x11)+(5x4)/(13x11)
=5/13x7/11+5/13x4/11
=5/13x(7/11+4/11)
=5/13x(7+4)/11
=5/13x11/11
=5/13
