Notice that when we cancel common factors of ten (zeros), we are limited by the number that contains the LEAST number of them. So in this case, we are limited by the number of zeros in the denominator (three zeros)
Answer: THREE zeros.
The answer becomes:
30,000/2
You cancel the zeros in PAIRS (one on top and one below the fraction line at a time)
In the case of
35,000,000 divided by 500 again we are limited by the number of zeros in the denominator (the one that contains less number of zeros). In such case, we cancel just TWO zeros.
350,000/5 is what we end up with after cancelling TWO zeros.
1.7 billion is written as:
1,700,000,000
1,280,000 is written as one million, two hundred eighty thousand.
43,900,000 is written as Forty three million nine hundred thousand.
