Answer 1

Răspuns:

⁴⁾1/12 < ³⁾5/16

12=3·2²

16=2⁴

cmmmc(12,16)=2⁴·3=16·3=48 → numitorul comun

4/48 < 15/48

_________________

³⁾5/8 > ²⁾6/12

8=2³

12=3·2²

cmmmc(8,12)=2³·3=8·3=24 → numitorul comun

15/24 > 12/24

__________

⁵⁾7/12 < ³⁾15/20

12=3·2²

20=2²·5

cmmmc(12,20)=2²·3·5=60 → numitorul comun

35/60 < 45/60

___________

³⁾11/12 > ²⁾6/18

12=3·2²

18=2·3²

cmmmc(12,18)=2²·3²=4·9=36 → numitorul comun

33/36 > 12/36

³⁾3/20 > ²⁾2/30

9/60 > 4/60
