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%.
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.

What is the percent decrease from the numbers 18.98 and 11.39?
To calculate the percent decrease between two numbers, you first need to find the difference between the two numbers. In this case, the difference between 18.98 and 11.39 is 7.59. Next, divide this difference by the original number (18.98) to get 0.399. Finally, multiply this result by 100 to get the percent decrease, which is approximately 39.9%.
What is the percent difference between 1419 and 1286?
To find the percent difference between two numbers, you first calculate the absolute difference between the two numbers. In this case, the absolute difference between 1419 and 1286 is 133. Next, you divide this absolute difference by the average of the two numbers (1352.5) and multiply by 100 to get the percent difference. Therefore, the percent difference between 1419 and 1286 is approximately 9.82%.
Who first found prime numbers?
The Egyptians were the first people to have some knowledge in prime numbers. Though, the earliest known record are Euclid's Elements, which contain the important theorem of prime numbers. The Ancient Greeks, including Euclid, were the first people to find prime numbers. Euclid constructed the Mersenne prime to work out the infinite number of primes.
