What is the LCM of 18 30 and 42?
To find the Least Common Multiple (LCM) of 18, 30, and 42, we first need to find the prime factorization of each number. 18 = 2 * 3^2 30 = 2 * 3 * 5 42 = 2 * 3 * 7 Then, we take the highest power of each prime factor that appears in any of the numbers. 2^1 * 3^2 * 5^1 * 7^1 = 2 * 3^2 * 5 * 7 = 630 Therefore, the LCM of 18, 30, and 42 is 630.
What is the percent of decrease from 60 to 42?
To calculate the percent decrease from 60 to 42, you first need to find the difference between the two numbers, which is 60 - 42 = 18. Then, divide the difference by the original number (60) to get the decimal decrease: 18 / 60 = 0.3. Finally, convert the decimal to a percentage by multiplying by 100: 0.3 * 100 = 30%. Therefore, the percent decrease from 60 to 42 is 30%.
What is the number between 18 and 42?
Thirty 42 - 18 = 24 24 / 2 = 12 18 + 12 = 30 42 - 12 = 30
