Math Topic 14.5 Understanding Ratios

CLICK HERE to play a game about understanding ratios.  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!!!
