To find the HCF you first need to break the numbers down into their prime factors. In this case you'd get: 3 = 3 15 = 3x5 The next step is to identify any common prime factors. In this case, the only common prime factor is 3. Therefore the HCF of 3 and 15 is 3.

To find the Least Common Multiple (LCM) of 15 and 30, we first need to find the prime factorization of each number. The prime factorization of 15 is 3 x 5, and the prime factorization of 30 is 2 x 3 x 5. To find the LCM, we take the highest power of each prime factor that appears in either number, which gives us 2 x 3 x 5 = 30. Therefore, the LCM of 15 and 30 is 30.
To solve 9/15 - 1/5 we need to get the denominators the same. We can see that 15 can be made from both denominators. 9/15 - 1/5 (3) 9/15 - 3/15 = 6/15 which simplifies to 2/5
There are 15 of them because 15/3 = 5

You can take 225 to 15 and 15. Then take 15 to 3 and 5. So, you have 3, 3, 5, 5.
7AM to 10PM is 15 hours. If you take meds at 7AM you need to take 4 more times over 15 hours, or every 15/4 = 3 and 3/4 hours or 3 hours and 45 minutes. So you take at 7AM, 10:45AM, 2:30PM, 6:15 PM, and 10PM
To find the HCF you first need to break the numbers down into their prime factors. In this case you'd get: 3 = 3 15 = 3x5 The next step is to identify any common prime factors. In this case, the only common prime factor is 3. Therefore the HCF of 3 and 15 is 3.

To convert feet to yards, you need to know that 1 yard is equal to 3 feet. To convert 15 feet to yards, you would divide 15 by 3, which equals 5 yards. Therefore, 15 feet is equivalent to 5 yards.

To find what you need to take from 13 to get -2, you can set up the equation: ( 13 - x = -2 ). Solving for ( x ) gives ( x = 15 ). Therefore, you need to take 15 from 13 to arrive at -2.
