A ratio is done by setting a relationship between two values using a colon. It is usally explained using a description:description and then you must input the values given for that description.
3.) Since this one has the descriptions of diet and regular sodas and there are 7 and 8 correspondingly, there are two different ratios that can be set up.
diet:regular = 7:8
This means that there are 7 diet sodas for every 8 regular sodas.
Or
regular:diet = 8:7
This means there are 8 regular sodas for every 7 diet sodas.
With this information, the only correct answer is A!
4.)Since this one has the descriptions of green and red apples and there are 5 and 7 correspondingly, there are two different ratios that can be set up.
green:red = 5:7
This means that there are 5 green apples for every 7 red apples.
Or
red:green= 7:5
This means there are 7 red apples for every 5 green apples.
With this information, there are actually two correct answers of B and D.
5.)Since this one has the descriptions of texts and calls made and there are 9 and 3 correspondingly, there are two different ratios that can be set up.
texts:calls = 9:3
This means that there are 9 texts for every 3 calls made.
Or
calls:texts = 3:9
This means that there are 3 calls for every 9 texts made.
With this information, the only correct answer is B!
I hope this helps!
