15/5 = 3 C O'Riordan
10/15 + 3/15 = 13/15 13/15
Three fifths of 25 is 15.
If you divide 25 by 5 then you get the the answer 5. Thus 5 is 1 5th of 25. If you multiply 5 by 3 you get the answer 15 15 is therefore 3 5ths of 25.
1/5 + 1/3 = 8/15
15/5=3
15/5 = 3 C O'Riordan
1/5th of 15 is 15/5 which is 3. So 3/5ths of 15 = 3 x 3, which is 9.
10/15 + 3/15 = 13/15 13/15
Three fifths of 25 is 15.
Three-fifths of 15 is 9.

15 x 3 = 45 15 x 5 = 74 15 x 7 = 105
If you divide 25 by 5 then you get the the answer 5. Thus 5 is 1 5th of 25. If you multiply 5 by 3 you get the answer 15 15 is therefore 3 5ths of 25.
1/5 + 1/3 = 8/15
24/20 - 15/20 = 9/20
To do this, you need to find the lowest commen denominator of 1/3 and 1/5. The lowest common multiple of the two denominators, 3 and 5 is 15, so you convert each fraction to a fraction with a denominator of fifteen and then add the numerators: (1/3) + (1/5) =(5/15) + (3/15) =(5+3)/15 =8/15 Therefore your answer is eight fifteenths.
