Final answer:
To find the multiples of 20, 12, 15, and 14 that are less than 100, list the multiples of each number stopping once a multiple is greater than 100.
Step-by-step explanation:
To find the multiples that are less than 100 for the numbers 20, 12, 15, and 14, we can start by listing the multiples of each number and stopping when we reach a multiple that is greater than 100.
The multiples of 20 less than 100 are: 20, 40, 60, 80.
The multiples of 12 less than 100 are: 12, 24, 36, 48, 60, 72, 84, 96.
The multiples of 15 less than 100 are: 15, 30, 45, 60, 75, 90.
The multiples of 14 less than 100 are: 14, 28, 42, 56, 70, 84, 98.
