**Reiny**, Sunday, November 13, 2011 at 9:24pmI 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

**Ms. Sue**, Sunday, November 13, 2011 at 9:24pmI'll get you started.

1. 12/21=X/7

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.
