Camp big trees has 3 red canoes and 4 blue canoes what fraction of the canoes are red

The fraction of red canoes he has is   3/7    because you add them all together and put the number of red ones on top         this can also be written as .43 or 43% when rounded

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
