Answer 3

To solve the expression, you need to follow the order of operations, which is usually remembered by the acronym PEMDAS:

P: Parentheses E: Exponents MD: Multiplication and Division (from left to right) AS: Addition and Subtraction (from left to right)

Now let's solve the expression step by step:

1. Simplify the expression inside the parentheses: (3/5 - 4/15)

To subtract fractions, we need a common denominator, which in this case is 15: (3/5 - 4/15) = (9/15 - 4/15) = 5/15

2. Now the expression becomes: 8/9 : 5/15

3. To divide fractions, we can multiply by the reciprocal of the second fraction: 8/9 * 15/5

4. Simplify the fractions before multiplying: 8/9 * 3/1

5. Multiply the numerators and denominators: (8 * 3) / (9 * 1) = 24 / 9

6. Simplify the fraction: 24/9 = 8/3

So, the solution is 8/3.
