Write the number pictured as a fraction and a decimal
Strategies[]
Knowledge of the relationship between decimals and fraction is encouraged to ensure success on this exercise.
- The problem always requests the fraction form first.
- The fraction is not required to be simplified.
- It can be more efficient to represent the fraction un-simplified, such as leaving the fraction over 100 in the examples where the grid with 100 squares is provided.
Real-life Applications[]
- Fractions/decimals have uses in finance and science.
- Fractions are used in real life in many different ways, but they are most commonly used in the cooking, construction and science industries.
- Balancing one's checkbook requires decimals, and reading the stock market requires fractions.
- An ability to translate quickly and recognize the relationship between decimals and fractions is useful in almost any science.
- Decimals are very common in shopping. Price tags, food labels, and receipts all contain decimals.
- At gas pumps, decimals are used to show how much gas is pumped and much it costs per gallon.
