Show transcript
Improper fractions can be added and subtracted in the same way as proper fractions. When interpreting data or solving problems, number-sense is needed to determine the most efficient strategy to use. Decide on the most efficient strategy by looking at the fractions of the minuend and subtrahend. Bar models are a useful tool to represent word problems and support in forming an equation to solve.
