To find out how many baby bunnies the rabbit has, we need to determine the greatest common divisor (GCD) of 90 carrots and 72 leaves of lettuce. The GCD will give us the maximum number of bunnies that can get an equal share of both carrots and lettuce without any leftovers.
Let's find the GCD of 90 and 72:
-
Prime factorization:
- 90 = 2 × 3^2 × 5
- 72 = 2^3 × 3^2
-
Identify the common prime factors:
- The common factors are:
- For 2: min(1, 3) = 1
- For 3: min(2, 2) = 2
- For 5: min(1, 0) = 0 (not common)
- The common factors are:
-
Calculating GCD:
- GCD = 2^1 × 3^2 = 2 × 9 = 18
The rabbit can divide the carrots and lettuce among 18 bunnies without any leftovers.
So the answer is B) 18.
