4th grade math I collect trains. 7 are blue and 23/30 are other colors. How many trains do I have?
You have 30 trains since 23 out of 30 are of other colors, while 7 of them are actually blue. This means that in total you have 23 plus 7, to get a total of 30 trains.
Fourth grade math? Are you 13 and just got held back a LOT, or are you helping someone else with theirs?
Count your own trains
