Megan's Scribe Post

Megan's Scribe Post~~ (im starting to like orange! XD)

Today we learned how to multiply fractions and make fractions easier to answer with numerator swap.

Multiplying



For example, if you get a fraction like 2/5 x 1/4, to get the answer, you could times the denominator by the other denominator and you would get the answer's denominator. Since you had already found the denominator for the answer, next step is to multiply the numerator by the other numerator. So lets see, Denominators = 5 x 4 = 20 so now it looks like this /20 without a numerator. Then since you have the denominator, you times the numerator, 2 x 1 = 2. So the answer is 2/20.


Simplifying



Now that you have the answer to the question, now you must simplify. To simplify, you use numbers that are divisible by both numbers. 2/20 seems to be both divisble by 2 you divide both of the numbers to simplify. 2 divided by 2 = 1. 20 divided by 2 = 10 so now the fraction looks like 1/10. You just simplified! Grats XD







Numerator/Wife...O.o Swap




To numerator/wife swap, at first, you would have to get a fraction like 3/4 and 4/9. You see how the number 4 is diagonal with the other 4? You can swap 4 with the 3 to make 4/4 x 3/9. You see that a fraction is the same number on both denominator and numerator right? Since this makes a whole, it = 1. So 4/4 means 1 x 3/9. 1 x 3/9 = 3/9 since you just had to multiply once and it ends with the same fraction. Now you need to simplify, both of the numbers are divisble by 3 so you divide both of the numbers by 3 and you got 1/3.


Yay I'm Done!!! XD

Yeah that's right Megan xP

'numerator/wife swap', lol so there's a denominator/wife swap too?

I like how you explain, multiplying fractions. Your explanation is better than Mr. Harbeck's.

Good Job Meg Double Eggs. ^o^
