Before you can do that, you have to put them all over the same denomanatr.
That's why math classes work on common factors and common multiples before
you get into adding fractions.
9 1/4 + 3/4
36/48
-3/13 is one such fraction.
They are alike because their exterior angles add up to 360 degrees They are different because the interior angles of a pentagon add up to 540 degrees and the interior angles of an octagon add up to 1080 degrees
Divide 2 by .25 and .25 by 2, add both up together and divide by 100
i give up i have been asking this question for 9 years a unlike fraction is where you have two or more fractions and the denominators are all different
A scalene triangle has 3 different side lengths and 3 interior angles that add up to 180 degrees.
It is a 3 sided shape of different lengths It has 3 interior angles of different sizes that add up to 180 degrees It has 3 exterior angles of different sizes that add up to 360 degrees
They're all different, but they still add up to 180.
It is 10/60, which can be simplified, if required. No point in simplifying if you want to add up lots of fractions of an hour, though.
A mixed number (or fraction).
When you add three of something to four of something, you get seven of something. It doesn't matter what the somethings are. Think of ninths as somethings. If you add three ninths and four ninths, you have to wind up with seven ninths. You can't wind up with seven eighteenths, because you weren't adding eighteenths to begin with.
