### Josh's Blog Post

Mr.Backe the email you sent me for the invitation expired so I couldn't really do anything. Sorry for not clicking it a while back so I asked Alvin too let me use his blogger account to do my post.
So in class today we learned the following:add proper and improper fractions; when adding fractions, the denominators must agree, that is, they must be the same. When fractions do not have a common denominator, find a common denominator for both fractions before adding. Add only numerators and keep denominators the same.

1/4 + 1 / 4 = 1 + 1/4
= 2/4
= 1/2

When your subtracting fractions, your doing the same thing like adding. When subtracting fractions, denominators must stay the same. When fractions do not have a common denominator, find one for both fractions before adding. Add only numerators and keep denominators the same.

1/2 - 1 /6 = 3/6 - 1/6
= 2/6
= 1/3

2 1/4 + 3 1/4 = 2 + 3 + 1/4 + 1/4
= 5 2 / 4
= 5 1/2

SUBTRACTING MIXED NUMBERS :
when subtracting the whole numbers first deal with the fractions as you did in the previous example unless you need to re group.

6 1/5 - 3 5/10 = ( 6 - 3 ) + ( 1 /5 - 5 / 10 )
= 3 + ( 2/10 - 5/10 )
= 2 + ( 10/10 + 2/10 - 5 / 10 )
= 2 + 7/10
= 2 7/10

I'm done my blog thats all I can recall from today. Sorry, I couldn't use paint too make it more clearer wouldn't let me add image so I did it like that. Brendans got your next blog
