Math question: If you divide a number by 668, add the quotient to the original number, and then subtract 668, what is the result?

Let the number be x. The equation can be written as (x/668) + x - 668. Simplifying, we have (x + 668) - 668 = x. Therefore, the result is always equal to the original number x, regardless of its value. This shows that no matter which number you choose, the mentioned operations result in returning the original number.

Math Question: What is the result of dividing the sum of 668 and its double by the product of 668 and its quotient when divided by 4, then multiplied by 2?

To solve this question, let's break it down step by step. The sum of 668 and its double is 668 + (2 * 668) = 668 + 1336 = 2004. Now, let's calculate the quotient of 668 when divided by 4, which is 668 / 4 = 167. To find the product of 668 and its quotient, we multiply 668 and 167, resulting in 111556. Finally, multiplying this product by 2, we get 2 * 111556 = 223112. Therefore, the answer to the original question is 2004 divided by 223112, which is approximately 0.00898. The division of 2004 by 223112 can be expressed as a decimal approximation: 0.00898.

Math question: In how many different ways can the number 668 be expressed as the product of two positive integers?

In order to find all the ways to express 668 as a product of two positive integers, we need to find its prime factorization. The prime factorization of 668 can be obtained by dividing it successively by prime numbers, which are 2, 2, 167. Now, when a number is expressed as a product of its prime factors, it can be represented as combinations of these prime factors. Thus, the prime factorization of 668 is: 2² × 167. Since we want to find the number of ways to express 668 as a product of two positive integers, we can distribute these prime factors into two factors. For the first factor, we can have: 2⁰ × 167¹ = 1 × 167 = 167 (one way) For the second factor: 2² × 167⁰ = 4 × 1 = 4 (one way) Combining these two factors, we get: 167 × 4 = 668. Therefore, the number 668 can be expressed as a product of two positive integers in only one way, which is 167 × 4 = 668.
