Answer:
1.) 20% 2.) 39% 3.) True ; False ; True
Explanation:
For the first one, all you need to do is 14 / 70. which is 20%.
For the second one, you need to add 84 and 132. Which is 216. Next just do 84 / 216. Which will then give you 39% (yes I rounded it so don't worry)
And for the third one: True (there are 15 pets in total) ; False (as much as brothers can act like animals they are not lol) ; True (in this case the number of brothers is not necessary)
