22. (a) Is 3100 even or odd?
Even
Odd
Explain your answer.

Even

Step-by-step explanation:

An even number is a number that can be divisible by 2 without a remainder. An odd number can be divisible by 2 and it's remainder is 1.

Let's put that to the test!

3100/2=1550 R:0

R is the remainder, which is 0. So the quotient thereby proves that 3100 is even and not odd.

Hope this helps!

3100 is even

Step-by-step explanation:

To determine this, you need only look at the last digit. The even numbers would end in

2  4  6 8 and 0

The odd numbers are

1 3 5 7 9

so 316 is even. It ends in a 6

and 937 is odd. It ends in a 7

o is an even digit. 3100 is even

3^2 * 100 is that what you meant? You get 9 * 100 = 900

It's still even because it ends in 0.
