Lesson 3: Equivalent fractions

# Equivalent fraction visually

• 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.
• Absolutely! That's a great way to think about equivalent fractions. It's like taking a pizza and cutting it into different numbers of slices. No matter if you cut it into 2, 4, or 8 slices, if you eat half the pizza, you're still eating the same amount. It's just that the size of the slices changes.
• 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
• how would you find the equivelant to something like a fraction
• To find an equivalent fraction, you can multiply or divide the numerator and denominator by the same number.

For example, if you have the fraction 1/2, you can multiply the numerator and denominator by 2 to get 2/4. This is an equivalent fraction to 1/2.
• Brady's baby rabbit drinks less than 1/2 pint of water a day. which amount is less than 1/2?
4/8 4/7,2/3.3/16
How do you solve this problem?
• 4/8 4 is half of 8, so it's equal to 1/2
4/7 4 is more than half of 7, so it's more than 1/2
2/3 2 is more than half of 3, it's more than 1/2
3/16 3 is less then half of 16, so it's less than 1/2
Half of 16 is 8, and 3 is less than 8.

• Is this a good video?
• How is 1/2 bigger than 2/4?
• 1/2 is not bigger than 2/4. Say you had two bars of equal length. You cut one into two pieces and the other into four if you shaded in one of the pieces of the bar split in two, and you shaded two pieces of the bar split in to four, you would have shaded in the same amount, making them equal.

Another way is to simplify 2/4. Since the numerater (2, the number on top) and denominater (4, the number on the bottom) can both be divided by the number 2, you could divide the number on top and the number on the bottom by 2, you would get 1/2.

So, 1/2 is equal to 2/4. I know the explanation might be a bit complex, but over time, things well get easier.

Thank you!
