Answer:
Explanation:
Suppose you are standing on a street corner. Suppose that you are counting cars. You notice that there are only black ones and white ones. For every 3 black cars there are 4 white ones. Beginning ratios always look something like this.
Black to white = 3 to 4
This is more commonly written in two ways
- Black to White = 3/4
- Black:White:: 3:4
So what do you notice? You should see that a ratio is a fraction.
All ratios are fractions.
Now suppose you are still on the street counting cars again. Suppose you notice that after counting 70 cars, you get
- Black to White = 30:40
- Is that still 3/4?
- The answer is yes. You can multiply 3/4 by the same number on the top as you did on the bottom.
