Basic Ratio Scaling and Sharing Problems
Definition:
A ratio scaling problem asks you to find a new size or amount of something based on a given ratio. A ratio sharing problem asks you to divide a given amount into equal parts based on a given ratio.
Example:
Ratio Scaling:
If you have a piece of cloth that is 30 cm long and you want to make it 45 cm long, you can use the ratio scaling formula:
45 cm = 30 cm × 4/3
This means that you need to cut the cloth into 3 equal pieces and then sew the two longer pieces together to reach 45 cm.
Example:
Ratio Sharing:
If you have 15 identical tiles and you want to divide them into 3 equal groups, you can use the ratio sharing formula:
3 ÷ 15 = 0.2
This means that each group will contain 0.2 tiles each, giving each group the same amount of tiles
