Compare the size of 30 and 0.03.
Write the set {the vowels} as a roster.
Name the elements in the set {r, s, t, u, v}
Find the LCM for 2, 7, 12, and 20.
30 is more than 0.03. I'd rather have 30 dollars than 3 cents.

To compare the size of 30 and 0.03, you can use the concept of decimals.
30 is a whole number, while 0.03 is a decimal number. In order to compare them, you can convert 30 into a decimal by adding a decimal point at the end of the number. It becomes 30.00.
Now, compare 30.00 and 0.03. You can notice that 30.00 is a larger number than 0.03. Therefore, 30 is greater than 0.03.
To write the set {the vowels} as a roster, we need to identify the vowels in the English alphabet. The vowels are a, e, i, o, and u.
Thus, the set {the vowels} can be written as {a, e, i, o, u}.
To name the elements in the set {r, s, t, u, v}, we can simply list the elements as they are given in the set.
Therefore, the elements in the set {r, s, t, u, v} are r, s, t, u, and v.
To find the least common multiple (LCM) for 2, 7, 12, and 20, we will use the method of prime factorization.
First, let's find the prime factorization of each number:
- The prime factorization of 2 is 2
- The prime factorization of 7 is 7
- The prime factorization of 12 is 2 * 2 * 3
- The prime factorization of 20 is 2 * 2 * 5
Next, we identify the highest power of each prime factor that appears in any of the factorizations:
- The highest power of 2 is 2^2 = 4
- The highest power of 3 is 3^1 = 3
- The highest power of 5 is 5^1 = 5
- The highest power of 7 is 7^1 = 7
Finally, we multiply these highest powers together to find the LCM:
LCM = 2^2 * 3 * 5 * 7 = 4 * 3 * 5 * 7 = 420
Therefore, the LCM of 2, 7, 12, and 20 is 420.
