- Suma de fracciones:
❀ Primera suma:
[tex] \frac{2}{3} + \frac{9}{3} = \\ \\ \frac{2 + 9}{3} = \\ \\ \frac{11}{3} = 3 \frac{2}{3} [/tex]
❀ Segunda suma:
[tex] \frac{5}{3} + \frac{2}{4} = \\ \\ \frac{12 \div 3 \times 5 + 12 \div 4 \times 2}{12} = \\ \\ \frac{20 + 6}{12} = \\ \\ \frac{26}{12} = \frac{13}{6} = 2 \frac{1}{6} [/tex]
❀ Tercera suma:
[tex] \frac{5}{20} + \frac{5}{4} = \\ \\ \frac{20 \div 20 \times 5 + 20 \div 4 \times 5}{20} = \\ \\ \frac{5 + 25}{20} = \\ \\ \frac{30}{20} = \frac{3}{2} = 1 \frac{1}{2} [/tex]
