1.
(A).
In Quantity A, use a common denominator to add:
In Quantity B, multiply straight across both top and bottom (common
denominators are only needed for addition and subtraction). Cancel where
possible:
Quantity A is greater. (Be careful with negatives! The closer to 0 a negative
is, the greater it is.)
2.
(D).
This is a common GRE setup—the question presents several fractions
and one actual number. First find what fraction of the whole that number
represents, then solve for the total (call the total
m
). Notice that all the
denominators are primes, so they don’t share any factors. Therefore, the
common denominator is their product: 5 × 7 × 3 = 105.
The remaining 26 monsters represent
of the total monsters at the
convention:
26 =
m
× 26 =
m
105 × 2 =
m
210 =
