Question 1063851: Explain Equivalent Ratios
Answer by addingup(3677)   (Show Source):
You can put this solution on YOUR website! So first of all, a refresher: What is a ratio.
A ratio is a relationship between two numbers (usually involving some kind of measurement).
Examples:
A cookie recipe that calls for a ratio of 4:2 flour to sugar ratio means that for every 4 (cups, tablespoons, whatever) of flour you need 2 of sugar.
Another example:
When people drive, they travel at a certain speed. We usually refer to that speed as miles per hour. That's a ratio because it's a relationship between distance and time.
-------------------------------------------
Equivalent ratios
Going to the last example above, if you have been driving at 60 miles per hour you could express the speed/time relationship as a ratio of 60:1 or 60/1 and after 2 hours you will have gone 60*2 = 120. This, as a ratio, is 120:2.
In this case, 60:1 and 120:2 are equivalent ratios, they both express the same relationship of speed and time.
