7000 x 600 = 4200000
tell how you could use a number line to determine which of two numbers is greater
You could add 13.
An estimate for the quotient of a division problem is sometimes less than the actual quotient. This occurs when the divisor is rounded down or when the dividend is rounded down, which can lead to a smaller estimate. Conversely, if the divisor is rounded up or the dividend is rounded up, the estimate could be greater than the actual quotient. Thus, the relationship between the estimate and the actual quotient depends on how the numbers are rounded.
On a number line, the numbers start with zero and get larger as they move to the right, They are negative and get smaller as they move to the left from the zero. To find which number is greater, you can find the places of two numbers on the line and the one on the right is greater.
230 + 670 = 900
11.5 is bigger than 2.5 is.
Depends what the numbers actually represent. You could have 6 whole numbers or 46 parts of 1, as in 46/46.
5 or 10
I think it means to do the work and then estimate it. But it could also be estimate the divisor and dividend and then do the work after those two numbers are estimated.
Any prime numbers greater than 2 will be odd numbers. The difference between two odd numbers will be an even number. So, the difference between two prime (and odd) numbers could be 2, 4, or 6, of the numbers given. The difference could not be 3, 5, or 7.
To change the expression "7 8" (which seems to imply a mathematical operation between the two numbers) into a false number sentence, you could alter the operation or the numbers involved. For example, if we assume the operation is addition, changing it to "7 + 8 = 16" would be true, but if we instead write "7 + 8 = 14," it would become false. Alternatively, you could change the numbers themselves, such as writing "7 - 8 = 0," which is also false.
To use compatible numbers to estimate the solution for 2622, you can round the number to a nearby, easier-to-work-with figure. For instance, you could round 2622 to 2600 or 2700, depending on what operation you are performing. This makes mental calculations simpler and provides a quick approximation. By using compatible numbers, you can quickly gauge the reasonableness of your answers in various mathematical contexts.
