Question

< = > ?

7/8 ...... 7/10 ;          7/10 ...... 7/6 ;             1/3 ...... 1/10 ;          2/4 ...... 2/3

7/2x3 ...... 7/3x2                                      2x1/5 ...... 2:1/5

Answer 1

`7/8 > 7/10`

`7/10 < 7/6`

`1/3 > 1/10`

`2/4 < 2/3`

`7/(2xx3) = 7/(3xx2)`

`(2xx1)/5 = (2:1)/5`

Answer 2

`7/8 > 7/10`

`7/10 < 7/6`

`1/3 > 1/10`

`2/4 < 2/3`

`7/(3xx2) = 7/(2xx3)`

`(2 xx 1)/5 = (2:1)/5`

Answer 3

`7/8` và `7/10`

ta có `MSC : 80`

`7/8=(7xx10)/(8xx10)=70/80`

`7/10= (7xx8)/(10xx8)= 56/80`

`=> 7/8 ...>... 7/10`

`------------`

` 7/10 ...<... 7/6`

vì `MSC : 60`

`7/10=(7xx6)/(10xx6)= 42/60`

`7/6=(7xx10)/(6xx10)=70/60`

`-----------`

`1/3 ..>.... 1/10`

vì `MSC : 30`

`1/3=(1xx10)/(3xx10)=10/30`

`1/10=(1xx3)/(10xx3)=3/30`

`---------`

`2/4 ...<... 2/3`

vì `MSC : 12`

`2/4=(2xx3)/(4xx3)= 6/12`

`2/3=(2xx4)/(3xx4)= 8/12`

`-----------`

`7/2xx3 ...<... 7/3xx2`

vì 

`7/2 xx 3= 21/2`

`7/3xx2= 14/3`

`---------`

`2xx1/5 ...<... 2:1/5`

vì 

`2 xx 1/5=2/5`

`2 : 1/5= 2xx 5= 10`
