Math question: If 728 is divided by 7, what is the quotient?

We can find the quotient by dividing 728 by 7. When we divide, we get 104. Therefore, the quotient is 104. The quotient represents how many times 7 can go into 728 evenly. It is obtained by dividing the dividend (728) by the divisor (7).

Math question: What is the smallest positive integer that, when multiplied by 728, gives a three-digit number?

To find the smallest positive integer that, when multiplied by 728, gives a three-digit number, we need to divide 728 by the largest three-digit number, which is 999. Using long division, we get: 728 ÷ 999 = 0 remainder 728 Since the remainder is not zero, we need to add 1 to the quotient and multiply it by 999 to find the smallest three-digit number: (0 + 1) × 999 = 999 Therefore, the smallest positive integer that, when multiplied by 728, gives a three-digit number is 999.

Question: What is the square root of the number obtained by multiplying 728 by the sum of the first 5 prime numbers?

To find the square root of the product of 728 and the sum of the first 5 prime numbers, we need to first calculate the product of 728 and the sum of these prime numbers: 2 + 3 + 5 + 7 + 11 = 28. Multiplying 728 by 28 gives us 20384. Taking the square root of 20384, we find that it is equal to √20384 ≈ 142.906. Therefore, the square root of the number obtained by multiplying 728 by the sum of the first 5 prime numbers is approximately 142.906.
