The answer is 12
3 fifteenths minus 5 fifteenths equals minus 2 fifteenths.
25/45 + 6/45 = 31/45
12 fifteenths (sure?)19 fifteenths = 10 fifteenths (2/3) + 9 fifteenths (3/5)
Convert the fraction parts to like terms, in this case fifteenths. 2 thirds is 10 fifteenths. 1 fifth is 2 fifteenths. So the final resuls is 1 and 10 fifteenths minus three fifteenths which is 1 and 7 fifteenths.
That will all depend on what is meant by 'two fitenths' but if it is two fifteenths then the answer is: 272/45 or 6 and 2/45
2 fifths is 6 fifteenths, so 7 fifteenths minus 6 fifteenths is 1 fifteenth.
3 fourths divided by 2 fifteenths = 1.5
27/60=9/20=.45
Converting to fifteenths, it is 5 fifteenths - 6 fifteenths, which gives minus one fifteenth.
5/45 multiply 5/15 by three to get 15/45. then divide the 15 by three to get 5/45.
Two fifths = six fifteenths, two thirds = ten fifteenths...
