7000 x 600 = 4200000
tell how you could use a number line to determine which of two numbers is greater
You could add 13.
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
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.
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.
You can extend it indefinitely, depending on your patience!
Not enough information.
Four negative numbers greater than -3 would be: -2, -1, -4, -5. These numbers are considered negative because they are less than zero. When comparing negative numbers, the number closer to zero is considered greater.
