If Ally got 50.83 percent out of 100 on a test, what is her grade?

It would be 50.83 but hopefully the teacher rounds it up to a 51 but some teachers actually put the actual grade with decimals

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)
