The energy content of a chocolate bar is 1000 kJ. If you eat half, how much energy do you consume?

When you eat part of something, you get energy proportional to the portion you eat. The chocolate bar has 1000 kJ if you eat the whole thing, so eating half provides half that energy. Half of 1000 kJ is 500 kJ, so you’d consume 500 kJ. (If you ate the whole bar you'd get 1000 kJ; a quarter would be 250 kJ, and so on.)
