You're asking for 10 solutions in return for 5 points. The method of solution
is the same for all ten of them, so if you can do one, you can do them all.
I'll show you how to do three of them, and you'll be well on your way.
In every problem, the ratio is one number divided by the other one. If that
gives you a fraction, then you might have to simplify the fraction (reduce it
to lowest terms).
-- 4 adults, 12 children.
Ratio of adults to children is 4 divided by 12.
4/12 reduces to 1/3. Choice ' F ' .
-- 20 chickens, 2 roosters.
Ratio of roosters to chickens is 2 divided by 20 .
2/20 reduces to 1/10 . Choice ' G ' .
-- 25 scouts, 5 leaders
Ratio of scouts to leaders is 25 divided by 5 .
25/5 reduces to 5/1 .Choice ' J ' .
You're on your way. Good luck.
