The math video..

Hi!!

Today, Nata and me recorded the math video at the highschool...
I started, and I have to recorded it 4 times, I was so nervous...
The first time I didn't take a paper so we had to repeat..
The second time, Natalia laughed, so...
The third time, I said:and now we colour five sides" and I colour one..xD
and the final, this was good...so....I think we did good..
Natalia recorded I think like 3 times...because she said something bad, the second, because she laughed and the final, she did it good...


Well, I'm going to write my dash of math video:

Hi, we are Rachel and Nathalie of the secondary school Ciudad de Hércules..
I'm going to explaind you how to subtract fractions with the same denominator...here we go!

The first example:
5/8-3/8

Ok, we don't have to do anything with the denominator, we just have to subtract the numeratos, but we are going to do this with a picture..
so we draw a circle divided into 8 equals sides because is the denominator of both fractions..
Now, we have to colour 5 sides because is the numerator of the first fraction and 3 sideos os the five sides painted because is the numerator of the second fraction..
and we get 2/8 and we reduce it by the same number and we get 1/4 and this is the final fraction because we can't reduce it again...so bye...
