Multiples of 30

Accepted Solution

A:
Multiples of 30 Methods Methods for Finding Multiples: For a beginner, you can find the multiples of a number by skip-counting to the next number. For Instance, if you want to find the multiples of 30, you could start at 30, and keep adding 30 over and over: 30, 60, 90, 120, and so on. Each of these numbers is a multiple of 30. Typically, this works best only for smaller numbers, as adding larger numbers together over and over can be difficult. Another way to do this is to use multiplication. To find the first few multiples of 30, you could just multiply 30 by each number in sequence, first multiplying by 1, then 2, then 3, and so on, which we will outline below. What are the Multiples of 30? So, what are the multiples of 30? Let’s write it out using the multiplication method: 30 × 1 = 30 30 × 1 = 30 30 × 1 = 30 30 × 2 = 60 30 × 2 = 60 30 × 2 = 60 30 × 3 = 90 30 × 3 = 90 30 × 3 = 90 30 × 4 = 120 30 × 4 = 120 30 × 4 = 120 30 × 5 = 150 30 × 5 = 150 30 × 5 = 150 30 × 6 = 180 30 × 6 = 180 30 × 6 = 180 30 × 7 = 210 30 × 7 = 210 30 × 7 = 210 30 × 8 = 240 30 × 8 = 240 30 × 8 = 240 30 × 9 = 270 30 × 9 = 270 30 × 9 = 270 30 × 10 = 300 30 × 10 = 300 30 × 10 = 300 So, the first 10 multiples of 30 are: 30, 60, 90, 120, 150, 180, 210, 240, 270 and 300. There are an endless number of multiples of 30. You could choose any number to multiply by 30 to find a new multiple! Interesting Facts about Multiples • Every number is considered the smallest multiple of itself. • A multiple of a number is very often also the multiple of another number. This is because if you multiply two numbers together, the result is a multiple of both numbers. • All multiples of even numbers are even. • The multiples of odd numbers, in sequence, alternate between odd and even numbers. • You can also find the negative multiples of a number by multiplying by negative numbers. Practice Finding Multiples of Other Numbers Finding multiples of any number can be done using the same methods as outlined above.
