What proportion of the first 10000 natural numbers contain a 5?
271 of the first 1000 natural numbers contain at least one digit 5. That is 27.1 % of them.
How many numbers contain 9 from 1 to 999?
262. Here's how:Let's look at 1 to 99, where 18 number contain a 9 digit. First there is 1 to 89, which 8 numbers contain the nine: {9,19,29,...89}, then all ten of the 90's have a 9, so that's 18. The next 8 groups, [101-199], [201-299] ... [801-899] follow this same pattern. and finally all 100 of the numbers [900 - 999] contain a 9.So it is 100 + (9 x 18) = 262This assumes you mean whole numbers only, as decimals or rationals would create an infinite set of numbers (unless you limited it to a certain number of decimal places)
Find four consecutive odd integers whose sum is 184?
First, divide by the amount of numbers (184 divide 4 = 46) and then find the numbers on either side. In this case, they are 43,45,47,49.
What are the first five whole numbers?

How do you round numbers to the nearest whole percent on a calculator?
To round numbers to the nearest whole percent on a calculator, you first divide the number by 100 to convert it to a decimal. Then, multiply the decimal by 100 to convert it back to a percentage. Finally, round the percentage to the nearest whole number. For example, if you have the number 78.56, you would first divide by 100 to get 0.7856, then multiply by 100 to get 78.56%, which rounds to 79%.
