if a/b < c/d then ad < bc
so do the multiplications and check them out
or, convert all to decimal, then it's easy to compare.
or, as in the first one,
note that
27/19 is greater than 1 (the numerator is bigger than the denominator)
11/30 is less than 1
so clearly, 27/19 > 11/30
This kind of comparison is easy to do without any actual calculations
