Answer 2

To solve the given expression, let's break it down step by step:

Step 1: Simplify the fractions: 4 - 2/3 = 12/3 - 2/3 = 10/3

Step 2: Convert the mixed numbers to improper fractions: 1 1/2 = (2 * 1 + 1) / 2 = 3/2 3/4 (already in fraction form)

Step 3: Add the fractions inside the parentheses: 1 1/2 + 3/4 = 3/2 + 3/4

Step 4: Find a common denominator to add the fractions: The common denominator for 2 and 4 is 4. 3/2 can be multiplied by 2/2 to get the common denominator: 3/2 * 2/2 = 6/4

Now we have: 3/2 + 3/4 = 6/4 + 3/4 = 9/4

Step 5: Perform the multiplication: (10/3) × (9/4)

To multiply fractions, multiply the numerators together and the denominators together: (10/3) × (9/4) = (10 × 9) / (3 × 4) = 90/12

Step 6: Simplify the fraction: 90/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 6: 90/12 = (6 × 15) / (6 × 2) = 15/2

Therefore, the solution to the expression (4-2/3)×(1 1/2+3/4) is 15/2 or 7 1/2.
