Question

what do all the multiples of 10 have in common? every multiple of 10 has at least 1 zero at the end of the number and can be written using 10 as a factor? 1 time 2 times

Explanation:

Step1: Recall definition of multiples

Multiples of 10 are numbers like 10, 20, 30, etc. They are formed by multiplying 10 by integers.

Step2: Analyze end - digit property

Since 10 = 2×5, when we multiply 10 by any integer, the resulting multiple will have at least one zero at the end. For example, 3×10 = 30.

Step3: Analyze factor property

By definition, a multiple of 10 is a number that can be written as \(n\times10\) where \(n\) is an integer. So 10 is a factor 1 time.

Answer:

Every multiple of 10 has at least 1 zero at the end of the number and can be written using 10 as a factor 1 time.
