Mathematics

vazorg [7]3 years ago
3 0

Answer:

900

Step-by-step explanation:

3-digit natural numbers are whole numbers that range from 100 to 999 (3-digit because there are three numbers)

- 999 whole numbers from 1 to 999 (counting from 1, 2, 3, 4...897, 898, 899)

- 1 to 99 are 2-digit numbers, so you do not count them

  • 999 - 99 = 900

there are 900 3-digit natural numbers!  

comment or message me if you are still confused!

Do the ratios 5:3 and 13:8 form a proportion?
shepuryov [24]

Answer:

  No

Step-by-step explanation:

Each ratio is irreducible, and they are different. Hence they are not the same value, so cannot be a proportion. A proportion is two equal ratios.

  5 : 3 = 40 : 24

  13 : 8 = 39 : 24 . . . . not the same as 40 : 24

_____

<em>Examples of proportions</em>

  5/3 = 40/24 . . . is a proportion

  13/8 = 39/24 . . . is a proportion
