Fraction Question: I'm missing the concept

Answer 1

At a convention of monsters, 2/5 are red, 1/7 are blue, and 1/3 are green, and the remaining 26 are orange. How many monsters are attending the convention?

I know you get a common denominator fraction of 92/105 and then subtract 105-92 to get 13/105. Then you say 13/105 (m) = 26. But why did you change the 92/105 to 13/105? I know the two make 105/105 =1, but I don't understand why you change that fraction.

Answer 2

you can also change them to decimals, than change them back to fractions

Answer 3

But what did changing 92/105 to 13/105 do to help me solve the problem?

Answer 4

it looks like you divided the top but forgot to do the same to the bottom

Answer 5

No. The 26 monsters remaining support the 13/105.

Answer 6

Oh! They represent the 13/105. I see.
