Now here are a few questions and answers for you.
9/10 x 5/18=
You multiply the numerators then the denominators.
Now you simplify the answer
45/180 divided by 5 is 9/36
Simplify the answers even more
9/36 divided by 9 is 1/4
The final simplified answer is one fourth
14/3 x 6/7=
To help you answer this question you could switch the numerators because nothing would happen if you just switch the numerators around a little to make it look more friendly.
6/3 x 14/7=
As you can see I switched the numerators. 14 is now over 7 and 6 is now over 3.
6/3 x 14/7=2 x 2=4
The final answer is four.
