Which numbers would you choose to estimate the exact product of 2525?
I'd choose 20 and 30 and estimate the product at 600. The actual answer is 625.
How you would estimate the product of greater numbers in the operations 6893 x 556?
In your example, the easiest way to estimate the product would be to round each factor to the nearest 10, 100, 1,000 or whatever the factors are. So, for 6,893 * 556, round to 7,000 * 600 to get an estimate. Since both numbers are rounded up, you know your estimate will be high, but this is an easy way to get a close answer. To be specific here, 7,000 and 600 would be multiplied to get 4,200,000. You multiply the first digits together, and then add the total number of zeroes in each rounded number to your answer.
How do you know a product of any 2 numbers greater than 1 must be a composite number?
Because that product would have both of the two numbers as factors, giving it at least a total of 4.
If you wanted to find the largest possible product value of the sum of two numbers that equals the square root of 3 how would you do that?
The largest possible product of two numbers that add to give a greater number is half of that greater numbered, squared (where the two numbers are each half of the greater number). For the square root of 3, this would be ½ x √3 x ½ x √3 = ½ x ½ x 3 = ¼ x 3 = 0.75.
What is the least common multiple of two numbers that have no common factor greater than one?
It depends on what the numbers are. For example, if the prime numbers you were talking about were 3 and 7, the least common multiple would be 21. If your numbers were 2 and 3, it would be 6.
Estimate the product of 73 403?
The answer is 2,800. To estimate the product of 2 numbers, you round to the nearest ten or hundred. In this case, you would round 73 to 70, and 403 to 400, to make it easy to multiply. 70 x 400 = 2,800
What could be the product of two even numbers and an odd number each of which is greater than 1 I don't understand this problem HELP?
It would have to be an even number greater than one as well.
Is the product of two numbers greater than either number?
Sometimes, sometimes not see 20,000 X 0 = 0 would be less. 20,000 X 1 =20,000 would be the same and 20,000 X 2 = 40,000 would be greater.
Explain whether it is easier to estimate the product 13.72 x 47.28 by using compatible numbers or by rounding each factor to the nearest whole number?
Compatible numbers would be easier. Rounding gives you 14 x 47. Compatible numbers could be 13 x 50 which would be closer to the actual product.
Estimate 199 over198 plus 35 over 17 indicating if the actual answer is greater than or less the estimate?
199 over 198 estimate = 1 actual answer would be greater than 1 35 over 17 estimate = 1 actual answer would be greater than 1
How do you know that the product of any two numbers greater than i must be a composite number?
Prime numbers have only two factors: one and themselves. By definition, your product would have more than that: one, the product and at least the two numbers that created the product. It has to be composite.
The sum of 2 numbers is 25 and their product is 156 What are the numbers-?
If the sum of 2 numbers is 25 and their product is 156, the 2 numbers would be 12 and 13.
