If there is a total of 90 marbles, and we know that there is 60 blue marbles. We can assume that the remaining 30 marbles are red therefore the ratio of red to red marbles would be 60÷30, which is 2. Or the ratio is 60:30 which is reduced to 2:1.
Question 1:
For this case we have that by definition, the GCF of two numbers is the largest number that is a factor of both numbers. For example, the number 10 is the biggest factor that 50 and 30 have in common.
We must find the GCF of the following expression:
We look for the prime factorization of each number:
The GCF of the three numbers is 
So:
Answer:
Option C
Question 2:
For this case we have that by definition of power properties of the same base, that:
That is, for multiplication of powers of the same base, the same base is placed and the exponents are added.
So:
ANswer:
Option A
508.45 i think i multiplied the apr i may be wrong though i have math of finance so
Answer:
you would have to find the other value of the ratio.
If you look at the original ratio of 5:4, you can tell that 45 is just 8×5 and therefore you can also multiply 4×8 which would 32.

Answer:
We get that √48 = 2⋅2√3. Lastly, step three says to simplify, so we go ahead and multiply the 2⋅2 outside of the square root to get 4√3. That's it! We get that √48 = 4√3.
