Why is 1/6 greater than 1/8 but less than 1/3??
ollegr [7]
1/6 is greater than 1/8 but less than 1/3 because: think of 1 slice taken away from a pizza with 6 slices, now think of 1 slice taken away from a pizza with 8 slices. Do the same with the last pizza. Think how much space was taken away from each pizza.
