A greatest common factor is the largest number that goes into two or more numbers (in this case two). To find the GCF of two numbers, we have to find the prime factorization (how to express a number as a product of prime numbers) and then see which numbers are common in both of the prime factorizations.
11. The prime factorization of 12 is 3 * 2 * 2. The prime factorization of 18 is 3 * 3 * 2. Looking at the prime factorizations, we can see that both of them have 3 and 2. That means that the GCF is 3 * 2 which is 6.
12. The prime factorization of 48 is 2 * 2 * 2 * 2 * 3. The prime factorization of 80 is 2 * 2 * 2 * 2 * 5. We see that the numbers shared are 2, 2, 2, and 2. That means that the GCF is 2 * 2 * 2 * 2 or 16.
Let the Total Number of dogs Larry has be : D
Let the Total Number of cats Larry has be : C
Given : Larry sold 5 dogs
Remaining Number of dogs Larry has : D - 5
Given : Larry sold 4 cats
Remaining Number of cats Larry has : C - 4
Given : After selling 5 dogs and 4 cats, Larry still has more dogs than cats
D - 5 > C - 4
The answer would be B because you would divide the 5 numbers less than 5 (1, 2, 3, 4, and 5) by 12 and you get 0.416 repeating this rounding to 0.42
Answer:
1728/ 125
Step-by-step explanation:
The ratio of corresponding lengths of the figures = ratio of the square root of their areas.
So ratio of lengths = 12/5.
Now volume is 3 dimensional so the ratio is the cube of the lengths
= 12^3/5^3
= 1728/ 125.
Answer:
54cm
Step-by-step explanation:
8cm + 5cm + 14cm = 27 cm + 27 cm = 54 cm
