I will do #3
If I understand the instructions , it would go like this
4/14 = 20/y
20/70 = 20/y
so y = 70
I hope that you are taught "cross-multiplying" soon
then 4y = 280
y = 70

I'll get you started.
21/7 = 3
12/3 = 4
12/21 = 4/7
2. 12/16=6/Z = 3/4
I'll be glad to check your answers for the other two problems.
