Is 1800 in the 8 times tables?

Answer 1

Yes because 8 times 225 = 1800

To check for divisibility by 8 (ie whether a number is in the 8 times table):

add the four times the hundreds digit to twice the tens digit to the ones digit; if this sum is divisible by 8, then so is the original number (and so the original number is in the 8 times table).

For 1800 this gives 4 × 8 + 2 × 0 + 0 = 32 = 4 × 8, therefore 1800 is divisible by 8 (and thus in the 8 times table).
