A rabbit is packing lunches for his children. He has 90 carrots and 72 leaves of lettuce. If he is giving each bunny the same number of carrots and the same number of leaves of lettuce, how many baby bunnies must he have? He will have no extra vegetables after he packs the lunches.(1 point)

To find the number of baby bunnies, you need to find the greatest common divisor (GCD) of 90 and 72.
Prime factorization of 90: 2 * 3^2 * 5
Prime factorization of 72: 2^3 * 3^2
To find the GCD, take the minimum power of each prime factor: 2 * 3^2
GCD = 2 * 3^2 = 18
Therefore, the rabbit must have 18 baby bunnies.
