Distinguish between Average Propensity to Consume and Marginal Propensity to Consume

Distinguish between Average Propensity to Consume and Marginal Propensity to Consume. The value of which of these two can be greater than one and when?

Average Propensity to Consume is the ratio between total consumption © and total income (Y).
APC= C / Y

Marginal Propensity to Consume (MPC) is the ratio between change in consumption ($\Delta C$) and change in income ($\Delta Y$).
MPC= $\Delta C$ / $\Delta Y$
APC can be greater than one in a situation when C>Y.
