Domenic is nervous about his math quiz tomorrow. Can his brother help him???
I have a math quiz tomorrow and I am confused about adding and subtracting fractions.
What is wrong you seem so nervous?
That´s easy. Here, let me help you.
Here´s a visual model.
Imagine that I ate 2/8 of a cookie and you finished it. How much did you eat?
Well, the cookie is split into 8 pieces and I ate 2 of 8 or 2/8. So you would do 8 minus 2 so you get 6
So, it's like I have 6 pieces of the cookie and I combined it with your 2 pieces I would get a total of 8 pieces.
That is exactly right. You should be ready for your quiz tomorow.
You bet I am.
