答案和解析
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
=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
