Answer:
7/15
Explanation:
1. In order to subtract fractions with unlike denominators, you first need to find a common denominator.
The denominators 3 and 5 share a common factor of 15. In order to convert 2/3, multiply the fraction by 5/5 (whatever you do to the top, you must also do to the bottom). You multiply the bottom by 5 because 3 times 5 is 15.
Next, to convert 1/5 into a fraction with a denominator of 15, you must multiply the fraction by 3/3, because 5 times 3 is 15.
You should end up with 10/15 and 3/15.
2. Subtract the numerators.
10-3=7
3. Write the answer as 7/15.
