∙ 6y agoFractions that have the same size or the same value are called equivalent fractions. They represent the same amount or quantity, even though they may look different. For example, 1/2 and 2/4 are equivalent fractions because they both represent half of a whole.
The best way to think about equivalent fractions is that they are fractions that have the same overall value. Equivalent fractions represent the same part of a whole. For example, if we cut a pie exactly down the middle, into two equally sized pieces, one piece is the same as one half of the pie. And if another pie (the same size) is cut into 4 equal pieces, then two pieces of that pie represent the same amount of pie that 1/2 did. So we can say that 1/2 is equivalent (or equal) to 2/4.
say you were adding 3 / 4 to 7 / 8, if you make the denominators (lower parts) the same its easier to add the fractions, so 3 / 4 = 6 / 8, then add to 7 / 8 = 13 / 8 = one and five eighths
They have the same physical dimensions but not the same size. 1 horsepower = 746 watts .
Because that's what "absolute value" means. It's the size of the number regardless of which direction the number goes ... positive or negative. +42 and -42 go in opposite directions, but they're the same size. So they have the same absolute value.
The same as you would find the average of other numbers. Add all the numbers together, then divide by the size of the set - by the number that indicates how many numbers you have.
equivalent fraction
They are in the same order, by size, as their numerators.

This is converting fractions into equivalent fractions, which is achieved by multiplying (or dividing) the numerator (top number) and denominator (bottom number) by the same number. eg 2/6 → (2×2)/(6×2) = 4/12 eg 2/6 → (2×3)/(6×3) = 6/18 eg 2/6 → (2÷2)/(6÷2) = 1/3 Thus 2/6, 4/12, 6/18, 1/3 all represent the same value.
Compared to some other planets in the same galaxy, yes; it is actually fractions of the size of other planets in this galaxy
There are infinitely many. But, thanks to the strange behaviour of infinities, it set of fractions between 0 and 1 has the same cardinality (size) as the set of fractions between 0 and 100, or 0 and 10000000.

Because the denominator does not express a value, only the size of the parts being added or subtracted. You can think of integers as fractions with a denominator of 1. At any rate, 1/3 plus 1/3 = 2/3, as you can see with any sliced pizza. When you multiply fractions, the denominator is telling you to change the size of those parts, so that 1/2 of 1/3 is 1/6.
You can totally add fractions with unlike denominators. You have to first find the LCD (least common denominator) to make them the same denomintars. And then you can just simply add them. What you cannot do is add fractions with unlike denominators without changing them to fractions with like denominators. The reason being that you would be attempting to add fractions that are different sizes. 1/2 is not the same size as 1/3, so it would be like trying to add apples and oranges. You have to change them to a common size and that is the reason you have to find the least common denominator first. While you cannot add 1/2 and 1/3, you can add 3/6 and 2/6.
