For part (a), just make sure that the two fractions have the same denominator and you're good.
For part (b), I used units to represent the portion of students lined up in short/long rows. From there, I formed an equation that allows me to solve for the number of students in 1 short row. With that information, I am able to find the total pupils in all rows (both short and long).
