Answer 1

110/150

Explanation:

125/500 is smallest, since you can imagine the difference from 125 to 500 is much larger compared to the others! Then, 90/270 is second smallest, because 9/27 is simply one third. You can tell that 125/500 is smaller than one third, because 125x3 is less than 500. After that, we only have 56/100 and 110/150. We need the denominators to be the same.

56/100

110/150

100 is two thirds of 150. This means that we must divide the numerator by 2 and multiply it by three to balance the common denominator. 56/2 then x3 is 84, which is less than 110.

56/100 = 84/150

84/150 < 110/150

Therefore the largest fraction is the 110/150 school.
