幫我做做幾條數學題~急急急!

6又11分之4

= (6 + 4/11)

= 6 + 0.363636......

= 6.363636......

= 6.4(最接近值至兩個位)

6又5分4% . 6.4 . 64% . 6分5 . 64 排次序(大至小)

6又5分4% = (6 + 4/5)% = 6.8% = 0.068

6.4 = 6.4

64% = 64/100 = 0.64

6分5 = 5/6 = 0.8333......

64 = 64

64 > 6.4 > 0.8333......> 0.64 > 0.068

即 64 > 6.4 > 6分5 > 64% > 6又5分4%

4又11之6

= 4 + 6/11

= 4 + 0.545454......

= 4.545454......

= 4.5(兩位有效數字)

或 4.55 (小數點後2位)
