Question

Determine the quotient of the product of the prime numbers listed in the First Row divided by the sum of the prime numbers listed in the Second Row. Round your answer to the nearest whole number.

First Row: 0, 3, 21, 31, 41, 51, 61, 71, 81, 91
Second Row: 1, 2, 23, 33, 43, 53, 63, 73, 83, 93

Answer 1

Hey!
I have two things to say to you:
1) in your first row - you have there a zero listed. Zero is NOT A PRIME NUMBER.
2) This way or the other, don't you see that the answer will be zero?
0 * something * somthing.... over (anything but zero) will give you...
ZERO.

Answer 2

Since the first row contains 0 as an element, the product of all those elements will be 0, and that divided by the sum of the elements in the second row will still be 0.

So it's a trick question; no rounding is required, the answer is 0.

Alternatively, they want you to filter out the non-prime numbers and then do the indicated calculations. In this case we get
Primes in first row: 3, 31, 41, 61, 71
Primes in second row: 2, 23, 43, 53, 73, 83
Product of primes in first row: 16,514,103
Sum of primes in second row: 277
Quotient is 16,514,103 / 277 = 59617 194/277 ≈ 59617.7, so rounded to the nearest whole number will be 59,618.

Answer 3

Shouldn't that 2 in the second row be a 5? all the others (except your 0 and 1) are two away: 21 and 23, 61 and 63, etc. Did you type it wrong?

Answer 4

Answer A: Multiply all the numbers in the first row
Answer B: Add all the numbers in the second row

Divide A by B and round. This can be done using a calculator. Unless you have to show your work, it which case, do it by hand :)
