Bytelearn · Accepted Answer

Convert to multiplication:  Step 1: Convert the division of fractions to multiplication by using the reciprocal of the divisor. Calculation: $ \frac{2}{5} \div \frac{2}{3} = \frac{2}{5} \times \frac{3}{2} $Multiply numerators and denominators:  Step 2: Multiply the numerators and the denominators. Calculation: $ \frac{2 \times 3}{5 \times 2} = \frac{6}{10} $Simplify the fraction:  Step 3: Simplify the fraction obtained from the multiplication. Calculation: $ \frac{6}{10} = \frac{3}{5} $Subtract from 1/2:  Step 4: Subtract the result from Step 3 by $ \frac{1}{2} $. Calculation: $ \frac{3}{5} - \frac{1}{2} $Find common denominator:  Step 5: Find a common denominator for the fractions to subtract. Calculation: Common denominator of 5 and 2 is 10. $ \frac{3}{5} = \frac{6}{10} $ and $ \frac{1}{2} = \frac{5}{10} $Perform subtraction:  Step 6: Perform the subtraction with the common denominator. Calculation: $ \frac{6}{10} - \frac{5}{10} = \frac{1}{10} $
