Respuesta :

They added the denominators
2/5 + 5/6
12/30 + 25/30
37/30 or 1 and 7/30

A) they added the bottom numbers instead of multiplying.

B) so you multiply 5 by 6 then 6 by 5 to get 30 as the bottom number.

now, the 2 above the 5 also has to be multiplied by 6. vice versa.

so you should get 12/30 + 25/30 = 37/30 then make [tex]1\frac{7}{30}[/tex]

to get [tex]1\frac{7}{30}[/tex] its 30/30 to make 1 then you have 7 left.
