Answer 1

a: =3/5+8/15=9/15+8/15=17/15

b: x=2:5/3=2x3/5=6/5

Answer 2

a,=3/5+8/15

=9/15+8/15

=17/15

b,x.5/3=2

x=2:5/3

x=2.3/5

x=6/5

Answer 3

a/=3/5+8/15

=9/15+8/15

=17/15

b/x=2:5/3

x=2x3/5

x=6/5

:)

Answer 4

`a)3/5+2/3xx4/5=3/5+8/15=9/15+8/15=17/15`

`b)x xx5/3=2`

`x=2:5/3`

`x=2xx3/5`

`x=6/5`

Answer 5

` 3/5 + 2/3 xx 4/5`

` = 3/5 + 8/15`

` = 9/15 + 8/15`

` = 17/15`

 

` X xx 5/3 = 2`

` X =2 : 5/3`

` X = 2 xx 3/5`

` X = 6/5`

Answer 6

3/5 + 2/3 x 4/5 =3/5 + 8/15= 20 /15 =4/3

x x 5/3 =2

x=2:5/3

x=6/5

Answer 7

a)3/5 +2/3 x 4/5

 = 3/5 + 8/15

= 17/15

b)X * 5/3 = 2

          x    = 2 : 3/5

           x = 3/10

đúng ko

Answer 8

a/=3/5+8/15

=9/15+8/15

=17/15

b/x=2:5/3

x=2x3/5

x=6/5
