Answer 2

To solve this expression, follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction) to simplify step by step:

Given expression: (18/15 + 3/5) * 25/33

Step 1: Solve the fractions within the parentheses: 18/15 + 3/5

To add fractions, you need a common denominator. The least common multiple (LCM) of 15 and 5 is 15. So, let's rewrite the fractions with a common denominator:

(18/15) + (9/15) = 27/15

Step 2: Simplify the fraction: 27/15 = 9/5

Now we have: (9/5) * 25/33

Step 3: Multiply the fractions: (9/5) * (25/33) = (9 * 25) / (5 * 33) = 225 / 165

Step 4: Simplify the fraction: 225 / 165 = 15 / 11

So, the final result is 15/11.
