For Exercises 10-13, find two pairs of numbers with the given number as their least common multiple. (LCM)

10. 10 11. 36

12. 60 13. 105

To find two pairs of numbers with a given number as their least common multiple (LCM), we need to understand what LCM means. The LCM of two or more numbers is the smallest number that all the given numbers divide evenly into.

Let's go through each exercise and find two pairs of numbers for each given number.

Exercise 10: Find two pairs of numbers with 10 as their LCM.
To find the pairs, we need to list the multiples of 10 and choose two numbers that have 10 as their least common multiple.
Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100...
Two pairs of numbers with 10 as their LCM could be (10, 20) and (30, 40).

Exercise 11: Find two pairs of numbers with 36 as their LCM.
To find the pairs, we need to list the multiples of 36 and choose two numbers that have 36 as their least common multiple.
Multiples of 36: 36, 72, 108, 144, 180, 216, 252, 288, 324, 360...
Two pairs of numbers with 36 as their LCM could be (36, 72) and (108, 144).

Exercise 12: Find two pairs of numbers with 60 as their LCM.
To find the pairs, we need to list the multiples of 60 and choose two numbers that have 60 as their least common multiple.
Multiples of 60: 60, 120, 180, 240, 300, 360, 420, 480, 540, 600...
Two pairs of numbers with 60 as their LCM could be (60, 120) and (180, 240).

Exercise 13: Find two pairs of numbers with 105 as their LCM.
To find the pairs, we need to list the multiples of 105 and choose two numbers that have 105 as their least common multiple.
Multiples of 105: 105, 210, 315, 420, 525, 630, 735, 840, 945, 1050...
Two pairs of numbers with 105 as their LCM could be (105, 210) and (315, 420).

By listing the multiples of each given number and selecting two pairs with the given number as their LCM, we can find the answers to Exercises 10-13.

If I understand your question, both answers are wrong.
