I guess you mean:
17/15
------
13/15
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
= 22/13
= 19/13
21 / 45 = 7 / 15 seven fifteenths 7 over 15
3/7 x 13/15 = 39/105 = 13/35 Multiply the numerators and multiply the denominators: 3 x 13 = 39 7 x 15 = 105
The answer is fifteen over seven
Thirteen over seven
Eleven fifteenths minus ten fifteenths is equal to one fifteenth.
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.
6 over 13
21 / 45 = 7 / 15 seven fifteenths 7 over 15
7/15 = 0.46666 epeating
1.857143
We convert to fifteenths which gives six fifteenths minus five fifteenths, so the answer is one fifteenth.
3/7 x 13/15 = 39/105 = 13/35 Multiply the numerators and multiply the denominators: 3 x 13 = 39 7 x 15 = 105
The answer is fifteen over seven
one and six over seven
Thirteen over seven
