17. Ratios
Equivalent ratios are ratios that name the same comparison. You can find equivalent ratios by using a table or by multiplying or dividing both terms of a ratio by the same number.
What is the ratio of cartoons
to total number of videos?

18. Ratios
Equivalent ratios are ratios that name the same comparison. You can find equivalent ratios by using a table or by multiplying or dividing both terms of a ratio by the same number.
What is the ratio of cartoons
to total number of videos? 2/14
2 to 14 2:14
Another way to write 2:14 is 1:7 because 2:14 can be simplified to 1:7
