If the decimal point is .500 and up, we will be rounding up. If it is .499 and lower, we will be rounding down. Now let’s look at the numbers. 2.500 g can be rounded up, so we’ll make that 3.000 g. 5.000 g is going to stay the same, since the decimal point is .000 2.268 g will be rounded down, making it 2.000 g 5.670 will be rounded up and will become 6.000 g And finally, 11.340 g will be rounded down to 11.000 g.
