Problem: 8/9 * (2/5+3/7*1/3+3/5) * 4 =?

8/9 * (2/5 + 3/7 * 1/3 + 3/5) * 4 =

Perform the multiplication inside the parentheses.
8/9 * (2/5 + (3/7 * 1/3) + 3/5) * 4 =
8/9 * (2/5 + 1/7 + 3/5) * 4 =

Convert the fractions inside the parentheses to a common denominator.
8/9 * (14/35 + 5/35 + 21/35) * 4 =

Add the fractions inside the parentheses.
8/9 * 40/35 * 4 =

Multiply the fractions.
(8/9 * 40/35) * 4 =

Perform the final multiplication and reduce the resulting fraction.
