Question

六上数学题，求助，谢谢

脱式计算：
36.08-1.4X16

5.1X99+5.1

34/5-5/3-7/3

2/13+5/14+9/13+9/14

31X0.75+31X0.25要脱式 过程

Answer 1

36.08-1.4X16
=36.08-22.4
=13.68
5.1X99+5.1
=5.1X(99+1)
=5.1X100
=510
34/5-5/3-7/3
=34/5-(5/3+7/3)
=6.8-4
=2.8
2/13+5/14+9/13+9/14
=(2/13+9/13)+(5/14+9/14)
=11/13+1
=1又11/13
31X0.75+31X0.25
=31X（0.75+0.25）
=31X1
=31

Answer 2

（1）36.08-1.4*16 = 13.68
（2）5.1*99+5.1 = 510
（3）34/5-5/3-7/3 = 2.8
（4）2/13+5/14+9/13+9/14 = 1.8461538461538
祝你开心，谢谢！你发的题好像不对！

Answer 3

36.08-1.4X16=4*9.02-1.4*4*4=4*（9.02-5.6）=4*3.42=13.68

5.18（99+1）=518

34/5-(5/3+7/3)=34/5-4=14/5

(9+2)/13+(5+9)/14=24/13

31*(0.75+0.25)=31
