Math Problem Statement

2 3/8 ÷ 3 1/2 = 19/8 × 2/7

Solution

The equation shown in the image can be solved step by step. Here's a breakdown of the problem:

  1. 238÷312=198×272 \frac{3}{8} \div 3 \frac{1}{2} = \frac{19}{8} \times \frac{2}{7}

Step-by-step solution:

  1. Convert mixed numbers to improper fractions:

    • 238=1982 \frac{3}{8} = \frac{19}{8}
    • 312=723 \frac{1}{2} = \frac{7}{2}
  2. Rewrite the equation: 198÷72=198×27\frac{19}{8} \div \frac{7}{2} = \frac{19}{8} \times \frac{2}{7}

  3. Multiply fractions: 198×27=19×28×7=3856\frac{19}{8} \times \frac{2}{7} = \frac{19 \times 2}{8 \times 7} = \frac{38}{56}

  4. Simplify the fraction: 3856=1928\frac{38}{56} = \frac{19}{28}

The final answer is 1928\frac{19}{28}.
