To locate the average (halfway point) between two fractions, change them both to equivalent fractions: fractions with a common denominator. The LCM is best, or you can multiply the denominators together to find a common one. Then add the fractions together and divide by 2.
If the numerator of the sum is odd, divide by two by multiplying the denominator by 2.
examples:
1/5 and 3/5 -- the average (halfway point) is obviously 2/5
1/3 and 2/3 -- the sum is 3/3 = 1, so the midway point is 1/2
(you can see that the midway point between 2/6 and 4/6 is 3/6)
1/5 and 3/7 -- 7/35 + 15/35 = 22/35 and the halfway point is 11/35
(the midway point between 7 and 15 is 11)
1/6 and 5/11 -- 11/66 + 30/66 = 41/66 and the halfway point is 41/132
Checking:
1/6 = 22/132 and 5/11 = 60/132 --
the midpoint 41/132 is 19/132 more than 1/6 and 19/132 less than 5/11
Convert them to equivalent fractions with a common denominator. Example: Halfway between 1/3 and 1/2 1/3 and 1/2 can become 2/6 and 3/6. There's no whole number between 2 and 3, so keep going to 4/12 and 6/12. Halfway between 1/3 and 1/2 is 5/12
a dot between 2 fractions is multiplication also the dot is another symbol to multiply
55. To find a number halfway between two numbers on the number line, add the two numbers together and divide by 2, so (82 + 28)/2 = 110/2 = 55. Check the answer: 55-28 = 27, and 82-55 = 27.Example: what is half way between 4 and 6 (the obvious answer is 5), but work it through: (4+6)/2 = 10/2 = 5.

you do what makes sense given the numbers, if the fractions work out beautifully, you can just leave them as mixed numbers, otherwise it's best to keep them as improper fractions

It just uses fractions instead of whole numbers. For example, if the numberline reaches between 0 and 1, the fraction 1/2 would be in the middle and 1/4 between 1/2 and 0.
you do the square root of the number
add both numbers and divide by 2. this gives the average, the centre number
Mathematical ratios are similar to fractions or decimals. It is the comparison between 2 different number of objects on either side to determine the equality between the two.
Convert them to improper fractions and proceed.
This is related to the fact that dividing by a number is the same as multiplying with the number's reciprocal.
To work out fractions on a calculator, you have to divide the top number (the numerator) by the bottom number (the denominator). Hope this helps, if it did leave a message on my message board H11pinky x
Mixed Fractions are fractions that have whole numbers and fractions on the side.If you are trying to change them into improper fractions you take the denominator of the fraction and multiply it by the whole number and keep the same numerator. ex.: 2 and one fourth =
a dot between 2 fractions is multiplication also the dot is another symbol to multiply
Add the two numbers together and divide that total by 2.
