Convert to the same units then a comparison can be made: 1 tonne = 1000 kg → 2 tonne = 2 × 1000 kg = 2000 kg 2000 < 3000 → 2000 kg < 3000 kg → 2 tonnes < 3000 kg 3000 kg is larger than 2 tonnes.
The PSP-1000 is much heavier than the 2000 and 3000. The PSP-2000 and 3000 are very similar though the 3000 has an antiglare screen, a built in microphone and the HOME button has been changed to the PS button.
The number that is in between 2000 and 3000 is 2500. This number falls exactly halfway between the two given numbers on the number line. It can be calculated by finding the average of the two endpoints: (2000 + 3000) / 2 = 2500.
