The answer would be -2/9w + 2/15
You first have to distribute the 1/3 to 2/5 (multiplication of fractions)
Then, distribute 1/3 to -2/3w (multiplication of fractions with an attached variable, which means simply multiply the fractions and add the variable at the end).
Remember: when multiplying fractions, multiply the numerators and denominators, the fractions do not have to have an equivalent denominator.
