what easier way can you find out 8 times 9?

Sagot :

Pull out 8 bags and fill them each with 9 apples

Answer & Step-by-step explanation:

8 is 2×2×2.

Doubling a number is the same as multiplying ×2.

So maybe you could take the 9 and double it, 18.

Double it again, 36.

Double it again, 72.

Or anyway that you can "take apart" 8 and 9 in smaller numbers and rearrange, because you can multiply in any order.

For example, if you don't know your 8 or 9 times tables, but you know your 3 and 4 and 6 times tables:

8 is 4×2 and

9 is 3×3.

8×9 is the same as 2×3 and 4×3

6×12

which is 72.

Hope this helps.
