At a used book sale , Ms Margo sees that 4 comic books cost $5. At the rate,how much book can ms Margo but for $15?

Nostrana [21]

12 books

What is the greatest common factor of 48, 24, and 45?

pshichka [43]

Answer:

Step-by-step explanation:

Let's write the factors:

48's factors are = 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48.

24's factors are = 1, 2, 3, 4, 6, 8, 12, 24.

45's factors are =1, 3, 5, 9, 15 and 45.

The greatest number that is in all three of these lists of factors is 3!

So, 3 is the greatest common factor between all three numbers!
