So.... you want to learn how to cross mulpy Hun?
Well you ask the right person!
first ask yourself this, What is Cross mulply?
cross mulpy is an easy way to find which fractions are bigger.
I'll show you the 5 easy steps of cross mulply.
1. write your fractions ON a piece of papper.
__3__ __5__
4 7 <--- example
2. put an X in the middle.
__3__ __5__
4 X 7
3. mulply the numbers diangle.
_3___ X _5___
4 7
7x3= 21
4x5= 20
4. write the anwser you mulpy on the top.
21 20
_3___ X _5___
4 7
7x3= 21
4x5= 20
5. Then look at the anwser you mulpy and see which one is bigger.
21 20
_3___ X _5___
4 7
7x3= 21
4x5= 20
6. the bigger number that is on top of the fraction is the anwser!
21 > 20
__3__ __5__
4 7
__3___
4 is bigger.
REMEMBER 1 :
you can use cross mulpy to see which fraction is bigger.
you can also use cross mulply to order fractions from least to greatests.
P.S.
I use cross Mulply on my Math test and I got an A+ and 100%
REMEMBER 2 :
You can only use cross mulpy with Fractions ONLY WITH FRACTIONS!
cross multipling
When comparing or simplifying fractions.
Cross canceling is a way to simplify or reduce fractions before multiplying them. For example, 2/4 x 1/6 can be reduced to 1/4 x 1/3 by cross canceling.
6/7 of 217
yes
No, it is quite possible for the fractions not to have common factors, even if you cross-cancel.
When you add or subtract fractions you cross multiply and when you multiply or divide fractions you across multiply.
to order fractions you can cross multiply two fractions at a time or you can convert all the fractions into decimals.
yes
Yes, because you can simplify the fractions then check the Cross products
No.

When doing fractions, you may cross multiply.
You do not need to.
