How would you solve 6+12/4

You add 6 and 12 and you get 20 and then divide it by 4 is 5

Oh gosh i love these questions. so, to find the proportion/unit rate, we do 12 shoelaces over 3 minutes i believe. we need to find x over y as our unit rate basically. so, write s (shoelaces) over m (minutes) a divide sign and then x (unit rate for shoelaces) over y (unit rate for minutes). i hope this is correct, else just look online for unit rate !
