Find what the question asks for and which unit it wants. If the units don't match, change one first. Then add, subtract, multiply or divide, and write the unit with the answer.

changemoney back after paying more than the price
Watch for: Mixing units, like adding minutes to hours without changing one. Finding the total cost but forgetting to take it from what was paid. Leaving off the unit.
At home: At the store, ask how much change you'd get from $20. When cooking, ask what time dinner is ready if it goes in now for 45 minutes.
