The first one is right and the third one is right, but you need to switch the 15% and the 95%.
In #2, it's asking for the kids that <em>are not</em> Michael, so it'd be 18/19. Which is then rounded to roughly 95%.
#4 asks for 6/40 = 15%
Answer:
12:19
Step-by-step explanation:
To create a ratio, we compare a portion to a whole. In this case our portion is 12 strawberries. Our whole is the total fruit, so let's add up each fruit to find the total.
12 + 3 + 4 = 19
Now we have our portion (12) and our total (19).
Let's create a ratio.
12:19
This ratio cannot be simplified further, so that is your answer.
Hope this helps!
