The question

Question: is 945 divisible by 2?

Is 945 divisible by 2?

Divisible means it goes in exactly, with nothing left over.

divisible: no remainder

1 Look at the last digit

= 945

945 is 94 tens and 5.

2 goes into 10, so into every ten.

Only the last digit is left to check.

94 tens + 5

For 2: is it even: 0, 2, 4, 6 or 8?

The last digit is 5.

So no.

= ÷ 2: last digit 0, 2, 4, 6, 8? 5 → no ✗

2 Write the answer

So 945 is not divisible by 2.

= no: 945 ÷ 2 has a remainder

3 Check

Let's check by dividing.

945 divided by 2 is 472, with 1 left over.

945 ÷ 2 = 472 r 1 (not divisible)

The tests were right!

Let's look back.

First: look at the last digit.

Then: write the answer.

Last: check.

Answer
