The average of a group of numbers is equal to the sum of the numbers divided by the number of numbers. If you want to find the sum of the five numbers, just multiply 790.6 by 5 to get the sum, which is 3953
To calculate two-thirds of a sum, you first find the sum of the numbers. Then, you multiply the sum by 2/3, which is the same as multiplying the sum by 2 and dividing by 3. This will give you the result of two-thirds of the sum. For example, if the sum is 15, two-thirds of the sum would be (15 x 2) / 3 = 10.
Well, darling, the sum of the first 99 odd numbers is 9801. You see, you take the last odd number, which is 197, multiply it by the total number of odd numbers (which is 99), and divide by 2. Voila! Math magic at its finest.
You can't write that as the sum of two prime numbers. Note: Goldbach's Conjecture (for expressing numbers as the sum of two prime numbers) applies to EVEN numbers.
The sum of the first 50 natural numbers is 1,251.
The numbers are: 11+ square root of 415 and 11 - square root of 415
The answer is 27+415= 422. It is as simple as that!
The average of a group of numbers is equal to the sum of the numbers divided by the number of numbers. If you want to find the sum of the five numbers, just multiply 790.6 by 5 to get the sum, which is 3953
These numbers go evenly into 415: 1, 5, 83, 415.
the product
It is 415 plus 375 equals 790
Avreage = Sum/number of values So 10 = sum/2 Multiply both sides by 2: 20 = sum
Either way, you'll end up with a rational number, but you won't get a sum if you multiply.
-6 and -9
multiply the mean by the amount of numbers
It's unclear whether you want two numbers that add to a sum or multiply to a product. 25 x 4 = 100 25 + 75 = 100
The numbers are -2 and 28
