Connected to environmental problems, we sometimes find numbers describing the impact some of them have over the population or the environment itself. Find an explanation below related to the use of numbers:

  • Compound numbers from 21 to 99 use a hyphen, as well as fractions:

35: Thirty-five

7/8: Seven- eighths 

  • Use a comma (not a point) for numbers with more than 3 digits:

1,000: one thousand

  • Use a point (not a comma) to include decimal numbers:

0.36: thirty-six cents

  • Do not use commas when writing numbers above 999:

2,321: two thousand three hundred twenty-one

  • It is not necessary to use the word and when writing numbers containing more than three digits. But, use the word and when introducing decimal numbers:

1,265.36: one thousand two hundred sixty-five and thirty-six
