use the ladder methad to find the lmc of12 and 28
To find the least common multiple (LCM) of 12 and 28 using the ladder method, follow these steps:
1. Write the two numbers, 12 and 28, on the left side of the ladder.
2. Start by factoring each number into its prime factors.
- The prime factorization of 12 is 2^2 * 3.
- The prime factorization of 28 is 2^2 * 7.
3. Write the common and uncommon factors on the rungs of the ladder.
____
2 | 12 <--- 2 is a common factor
2 | 6 <--- 2 is a common factor
3 | 3 <--- 3 is a common factor
4. Multiply the numbers on the right side of the ladder to get the LCM.
LCM of 12 and 28 = 2 * 2 * 3 * 7 = 84.
Therefore, the LCM of 12 and 28 is 84.
To find out how many hours Gary worked, we can use the formula:
Hours worked = Total earnings / Hourly rate
In this case, the total earnings are $310.42, and the hourly rate is $7.48.
Hours worked = $310.42 / $7.48
Using a calculator, we can find:
Hours worked ≈ 41.50
Therefore, Gary worked approximately 41.50 hours last week.
To find out how many hours Gary worked, we can divide his total earnings by his hourly wage.
We have the following information:
- Gary's hourly wage: $7.48
- Gary's total earnings last week: $310.42
To calculate the number of hours worked, we can use the formula:
Number of hours worked = Total earnings / Hourly wage
Plugging in the given values:
Number of hours worked = $310.42 / $7.48
Using a calculator, we can divide $310.42 by $7.48 to find the number of hours Gary worked.
Number of hours worked ≈ 41.5
Therefore, Gary worked approximately 41.5 hours last week.
