500
500 and 1000
1000
It rounds up to 1000 because 600 is greater than 500
1000 - 500 = 500. It's the same as asking: 1000 x 1/2.
500 * 1000 = 500,000
1000 milligrams = 1 gram so 500*1000 mg = 500*1000/1000 grams = 500 grams.
500
That is 1000 plus half of 1000, or 1000 + 500.
Since 1000 is a multiple of 500, it is automatically the LCM.
981,000
500 + 500 = 1000
500+500 = 1000
