Step-by-step explanation:
To work out the answer to the equation 2/3 - 1/5, you need to find a common denominator for the fractions. The common denominator for 3 and 5 is 15. So, you need to convert both fractions to have a denominator of 15. To convert 2/3 to have a denominator of 15, you multiply the numerator and denominator by 5, resulting in 10/15. To convert 1/5 to have a denominator of 15, you multiply the numerator and denominator by 3, resulting in 3/15. Then, subtract 3/15 from 10/15 to get 7/15. Therefore, the answer to the equation is c. 7/15.
