Answer 6

Now, suppose the values were not equal. Suppose you had

a/b _____ c/d

And

a(d) < b(c)

then

a/b < c/d

or if

a(d) > b(c)

then

a/b > c/d

Answer 7

You mean you have

13/20 _____ 7/10

and

(13)(10) ? (20)(7)
130 ? 140

Well
130 < 140

So what does that tell you?

greater

Answer 9

Type out completely what you believe using math characters. Don't just say "greater"

the words "greater" by itself means very little.

Answer 11

Basically, when you do the cross multiplication, you have to follow things precisely or you will get them wrong.
