Start by multiplying the fractions together. When multiplying fractions they don't need to have a common denominator, so multiply 2/8 and 4/9 from left to right.

Now your new problem looks like: 7/9 - 8/72. When subtracting fractions they have to have common denominators so multiply 7/9 by 8/8.

You can now subtract 56/72 and 8/72 to get your final answer.

This fraction can be simplified by dividing both sides by 8 because the numerator and denominator of this fraction are multiples of 8 and can be divided evenly by 8.

6/9 can be simplified even further by dividing both sides by 3 because both 6 and 9 can be divided evenly by 3.

D) 2/3 is your final answer.
