• I keep getting confused over what a denominator and a numerator is😟
• Have you heard of a "denomination"? People don't use this word much anymore, but when we paid with cash all the time, it was a common word. The denomination of a paper bill is, for example, a "twenty". The denomination of a coin is, for example, 25 cents. to describe a collection of money, we must use two numbers, not one. For example, I have 2 twenties. the two, is the count, or the "numerator". In the world of fractions, this means that if I have a bag with 1/4 (quarters), if I want to label the bag, I have to use 2 numbers, somewhere I need to write quarter, and somewhere I have to write how many quarters are in the bag. So we have all agreed (about 1,500 years ago) to label a bag with three quarters, 3/4. The count goes on the top (or on the left) and the denomination, the number of pieces the whole was cut into (the denominator) goes on the bottom (or the right).
• i still don't get this can u make another video for dumb people like me
• how do you get a equivalent fraction
• 1/2 = 2/4; 2/3 = 4/6, 3/4 = 6/8, 4/8 = 8/16 etc.
• how do we even do this, i don't understand the question...
• can you add fractiones if the dominater is diffrent in 4 grade

• No, you can't add fractions with different denominators. You can change the fractions so that they both get the same denominators, but until you do, you can't solve the problem.
• What is one thing that kids most likely 6th graders always have trouble with. Or might need help with
• You can also divided the fraction both if it divisble by a number.
• im so confused how did he get 3 for the numerator and the denominator.
