The expressions have the same expansion I'd say because the pairs 2 and 30, 3 and 20, and 4 and 15 because they are all equivalent to 60 because they are all factors of 60.
Same goes with the other pairs, because they are all equivalent to 48 because they are all factors of 48.
I believe the answer is 28/40 which is reduced to 7/10.
It says large OR blue, so i added the total of large + blue, and its out of 40 total so i got 28/40. that reduces to 7/10.
