Question

Guys help me please!

Answer 1

Answer:

Step-by-step 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.

That's as much as I want to give you at this time. If you want more, be sure put  a comment at the end of this question. If you do it within an hour, I'll just edit the question. Otherwise, I'll use comments.
