I guess you mean:
which is the same as:
17/15 ÷ 13/15
First: convert the mixed number to an improper fraction, then change the divide to multiply and invert the second fraction; do the multiplication and convert any improper fraction to a mixed number:
17/15 ÷ 13/15 = 22/15 ÷ 13/15
= 22/15 x 15/13
Eight over fifteen is. If you could get used to calling those fractions "seven fifteenths" and "one fifteenth", then you'd quickly realize that 7 of anything plus 1 of the same thing is 8 of them.
Thirteen fifteenths is equal to 86.66666(repeating).
1/5 - 2/3 = 3/15 - 10/15 = -7/15 Negative seven over fifteen. Negative seven fifteenths.
Example: If there are fifteen slices of a pizza, and thirteen of them are shaded, the two more slices that you have to shade for thirteen over fifteen are smaller than the one slice that you have to shade, already making it bigger if you have to shade less.
6 over 13
We convert to fifteenths which gives six fifteenths minus five fifteenths, so the answer is one fifteenth.
7/15 = 0.46666 epeating
21 / 45 = 7 / 15 seven fifteenths 7 over 15
The answer is fifteen over seven
Eleven fifteenths minus ten fifteenths is equal to one fifteenth.
