• How do you add two factors with denominators of 12 and 31?
• find a common denominator and whatever you do to the bottom you have to do to the top
• So would it be as if we were just cutting them to look just like each other to see if each of them are the same.
• This video didn't really make sense to me can anyone help me understand it a little more? 😅😅😅
• Hey! So basically you just need to remember that it does not matter what parts of the circle you shade in as long as it is the same amount and that it is the same size of slices, and that to simplify a fraction find a number that you can divide the bottom and the ton by and then divide the top and bottom by that SAME number. Do not make decimals on fractions until you get to Algebra I. And really, not even then.
• i know you explained that 1/5 is equal to 2/10, but since 4/5 of the first circle are shaded in does that mean that the first "pie" could represent 4/5 as well as 1/5?
• Yes it could, depending on which way you see it.If the unshaded part represents how much you ate, the shaded part may represent how much you had left.While the values would of course be different, the pie could represent either the shaded or the unshaded part depending on what you want it to represent.
• What does equivalent mean
• It means the SAME. For example, 1/2 is equivalent to 4/8 or 10/20, or 50/100 :-) All of those can be made smaller (1/2) and look the same when you color them.

Equivalent= the same
• What makes 1/5 is the same as 2/10?
