To answer this problem you first find the GCF (Greatest common factor) between 60 and 72, which is 12. Next, to find how many rows of girls there are you divide 72 by 12. You get 6. There are 6 rows of girls. Next, you divide the number of boys which is 60 by twelve to find how many rows of boys there are and you get 5. there are 5 rows of boys.
If each row had 12 students in it you would divide both 72 and 60 by 12 
72/12=6 rows of girls
And 60/12=5 rows of boys
