I think you're saying that you want equivalent fractions for 4/5 and 5/6 ,
and the equivalent fractions should both have the same denominator. OK.
Have you learned "least common denominator" yet ?
Or maybe "least common multiple" ?
It's the smallest number that 5 and 6 both go into with no remainder.
I'm not going to try to explain the whole general method for finding it.
That confuse both of us, you and me.
In this case, I'll just tell you that the smallest common denominator here
is 30 . Now you have to find the two numerators, so that the new
fractions will really be equivalent to the old ones.
-- Write 4/5 as something with a denominator of 30 .
4/5 = ? / 30 .
What is the '5' multiplied by to get the '30' ?
It's multiplied by 6 to get 30 .
So multiply the 4 by the same 6. The equivalent fraction is 24/30 .
-- Write 5/6 as something with a denominator of 30 .
5/6 = ? / 30 .
What is the '6' multiplied by to get the '30' ?
It's multiplied by 5 to get 30 .
So multiply the 5 by the same 6. The equivalent fraction is 25/30 .
