The correct Answer is:
To solve the expression `((1)/(2) of 1(1)/(2)) div (3(1)/(2) - 1(1)/(4)) of 1(1)/(2) - 1(1)/(2) div 2(1)/(4) + 1(1)/(3)`, we will follow the order of operations, often referred to as BODMAS/BIDMAS (Brackets, Orders, Division/Multiplication, Addition/Subtraction). ### Step-by-Step Solution: 1. **Convert Mixed Numbers to Improper Fractions:** - \( 1(1/2) = \frac{3}{2} \) - \( 2(1/4) = \frac{9}{4} \) - \( 1(1/3) = \frac{4}{3} \) The expression now looks like: \[ \left(\frac{1}{2} \cdot \frac{3}{2}\right) \div \left(\frac{3}{2} - \frac{1}{4}\right) \cdot \frac{3}{2} - \frac{3}{2} \div \frac{9}{4} + \frac{4}{3} \] 2. **Calculate the First Part:** - Calculate \( \frac{1}{2} \cdot \frac{3}{2} = \frac{3}{4} \) Now the expression is: \[ \frac{3}{4} \div \left(\frac{3}{2} - \frac{1}{4}\right) \cdot \frac{3}{2} - \frac{3}{2} \div \frac{9}{4} + \frac{4}{3} \] 3. **Calculate the Denominator of the First Division:** - Find a common denominator for \( \frac{3}{2} - \frac{1}{4} \): - The common denominator is 4. - Convert \( \frac{3}{2} = \frac{6}{4} \) - Now, \( \frac{6}{4} - \frac{1}{4} = \frac{5}{4} \) The expression now looks like: \[ \frac{3}{4} \div \frac{5}{4} \cdot \frac{3}{2} - \frac{3}{2} \div \frac{9}{4} + \frac{4}{3} \] 4. **Perform the Division:** - \( \frac{3}{4} \div \frac{5}{4} = \frac{3}{4} \cdot \frac{4}{5} = \frac{3}{5} \) The expression now simplifies to: \[ \frac{3}{5} \cdot \frac{3}{2} - \frac{3}{2} \div \frac{9}{4} + \frac{4}{3} \] 5. **Calculate the Multiplication:** - \( \frac{3}{5} \cdot \frac{3}{2} = \frac{9}{10} \) The expression now looks like: \[ \frac{9}{10} - \frac{3}{2} \div \frac{9}{4} + \frac{4}{3} \] 6. **Perform the Division:** - \( \frac{3}{2} \div \frac{9}{4} = \frac{3}{2} \cdot \frac{4}{9} = \frac{12}{18} = \frac{2}{3} \) The expression now simplifies to: \[ \frac{9}{10} - \frac{2}{3} + \frac{4}{3} \] 7. **Combine the Terms:** - Combine \( -\frac{2}{3} + \frac{4}{3} = \frac{2}{3} \) The expression now looks like: \[ \frac{9}{10} + \frac{2}{3} \] 8. **Find a Common Denominator:** - The common denominator for \( 10 \) and \( 3 \) is \( 30 \). - Convert \( \frac{9}{10} = \frac{27}{30} \) - Convert \( \frac{2}{3} = \frac{20}{30} \) Now, add the fractions: \[ \frac{27}{30} + \frac{20}{30} = \frac{47}{30} \] ### Final Answer: The value of the expression is \( \frac{47}{30} \).
