What do you already know about ratios? What do ratios tell us?
Ratios are a comparison of two numbers or quantities. They can be written with a fraction bar, the word "to", or even a symbol : (which we call a colon)
Example: If I have 6 blue marbles in a bag and 4 read marbles in a bag, the ratio of blue to red would be written in one of these ways: 6:4, 6 to 4, or 6/4.
Did you know??? 3:2, 3 to 2 and 3/2 would be equivalent ratios to 6:4. How do you know???
This will be helpful information for the math test that we will be taking on Monday. Good luck!!!
