Answer 1

1/3=5/15
1/5=3/15
2/3=10/15
2/5=6/15
3/5=9/15
4/5=12/15

Answer 2

To find out how many fifteenths are contained in each of the given fractions, we can convert them all to a common denominator of 15. Let's calculate it step by step:

1/3 can be multiplied by 5/5 to get a denominator of 15: (1/3) * (5/5) = 5/15.

1/5 can be multiplied by 3/3 to get a denominator of 15: (1/5) * (3/3) = 3/15.

2/3 can be multiplied by 5/5 to get a denominator of 15: (2/3) * (5/5) = 10/15.

2/5 can be multiplied by 3/3 to get a denominator of 15: (2/5) * (3/3) = 6/15.

3/5 remains the same as it already has a denominator of 5: 3/5.

4/5 remains the same as it already has a denominator of 5: 4/5.

Now, we can see how many fifteenths are in each fraction:

1/3 = 5/15 (5 fifteenths) 1/5 = 3/15 (3 fifteenths) 2/3 = 10/15 (10 fifteenths) 2/5 = 6/15 (6 fifteenths) 3/5 = 3/5 (not in fifteenths, as it already has a denominator of 5) 4/5 = 4/5 (not in fifteenths, as it already has a denominator of 5)

So, in summary:

1/3 contains 5 fifteenths. 1/5 contains 3 fifteenths. 2/3 contains 10 fifteenths. 2/5 contains 6 fifteenths. 3/5 does not contain fifteenths, as it already has a denominator of 5. 4/5 does not contain fifteenths, as it already has a denominator of 5.
