Answer:
The GCF is going to be 20
Step-by-step explanation:
This Is how I find the GCF of 2 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here
The prime factorization of 20, 2 × 2 × 5= 20
The prime factorization of 80, 2 × 2 × 2 × 2 × 5 = 80
The common factors are 2, 2, and 5. We multiply those to get the GCF.
2 × 2 × 5 = 20

Answer:
for every 2 biographies you put 1 mystery book until you get to the middle then there will be 3
Step-by-step explanation:
The correct answer should be A because you have to have a common denominator in order to solve so you take 5/6x and 4/6x and solve.
