I haven't touched on mean, mode, medium, and range in a little while so I could be wrong, but if (mean) means average, i think average is adding 2 grades together then dividing the number of exams, so the average needs to be 90, so what I did was i found the difference between the original grade on the first exam, so 90-86=4, so i guessed at 94 being the next grade needed. (86+94)/2=90. 86+94=180 then divide 180 by 2 and it equals 90. so yeah your answer is 94.
I think he would be 4 away from zero
7 1/4 - 5 3/4= 1 1/2 because you can either 1) change it into decimals: 7.25-5.75 and do simple subtraction or... 2) u can change the 7 to a 6 and add 4 to the numerator of 1/4 making the equation 6 5/4 - 5 3/4 = 1 2/4 which simplified to 1 1/2 I hope I didn’t confuse you! :))
