Step-by-step Solution

Para resolver estas divisiones, primero necesitamos convertir las fracciones mixtas en fracciones improperas. Luego, podemos realizar la división. 1. \( 3 \frac{1}{4} \div \frac{7}{8} \) Primero, convertimos \( 3 \frac{1}{4} \) a una fracción impropera: \[ 3 \frac{1}{4} = \frac{3 \times 4 + 1}{4} = \frac{13}{4} \] Ahora, realizamos la división: \[ \frac{13}{4} \div \frac{7}{8} = \frac{13}{4} \times \frac{8}{7} = \frac{13 \times 8}{4 \times 7} = \frac{104}{28} = \frac{26}{7} \] Por lo tanto, \( 3 \frac{1}{4} \div \frac{7}{8} = \frac{26}{7} \). 2. \( 2 \frac{7}{9} \div 3 \frac{2}{5} \) Primero, convertimos \( 2 \frac{7}{9} \) y \( 3 \frac{2}{5} \) a fracciones improperas: \[ 2 \frac{7}{9} = \frac{2 \times 9 + 7}{9} = \frac{25}{9} \] \[ 3 \frac{2}{5} = \frac{3 \times 5 + 2}{5} = \frac{17}{5} \] Ahora, realizamos la división: \[ \frac{25}{9} \div \frac{17}{5} = \frac{25}{9} \times \frac{5}{17} = \frac{25 \times 5}{9 \times 17} = \frac{125}{153} \] Por lo tanto, \( 2 \frac{7}{9} \div 3 \frac{2}{5} = \frac{125}{153} \).

Quick Answer

1. \( 3 \frac{1}{4} \div \frac{7}{8} = \frac{26}{7} \) 2. \( 2 \frac{7}{9} \div 3 \frac{2}{5} = \frac{125}{153} \)
