How many tens are in 40000?

Answer 1

The answer is 4000.

To work it out, simply divide the larger number by the smaller. You can do that in 3 ways: a) as a standard division, b) by writing 40000/10 (an improper fraction) and cancelling, or c) by indices: since 40000 = 4 x 10^4 and 10 = 10^1 subtracting the indices gives you the answer in the same exponential format.
