Check understanding
- Write a ratio from a word problem and simplify it (e.g. 12:8 = 3:2)
- Convert a ratio to equivalent fractions of a whole (e.g. 3:2 means 3/5 and 2/5)
- Simplify ratios involving decimals or fractions by finding a common multiplier
“If a smoothie recipe uses orange juice and mango juice in the ratio 3:2, can your child simplify that ratio, express it as a fraction, and work out how much of each is needed for a given total amount?”
