When they each collect 3 cans and ms lees class has 1 less studen than mr galvezs class, how many more cans where collected by mr galvezs class? i would make a guess of 3 because if they each collect 3 and ms lees class has one less student then that would be the sort of question you ask, not '<span>How many more cans were collected by MR Galvezs class than Ms lees class' because it gives no info</span>
Since you're most likely not going to answer back, I can tell you the equation. Let's say Mr. Galvez's class is G and Ms. Lee's class is L. Whoever has the larger number goes first in the equation. Let's say G is the larger number. So:
G - L = X
X is the unknown number. Fill in the L and G to figure out how many more cans Mr. Galvez's class has than Ms. Lee's class! I hope this helps. :)
