Which of the following fraction is more 2/3, 7/8, 1/2, or 3/4

7/8 because if you plug it into a calculator you get 0.875 which is bigger than the rest of the fractions

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)
