Question

AYUDAA Calculá a.4/11÷7/9 b.5/12×3/10 c.13/1-5/2 d.4/3+5/9​

Answer 1

- Solución:

❀ División:

$\frac{4}{11} \div \frac{7}{9} = \\ \\ \frac{4 \times 9}{11 \times 7} = \\ \\ \frac{36}{77}$

❀ Multiplicación:

$\frac{5}{12} \times \frac{3}{10} = \\ \\ \frac{5 \times 3}{12 \times 10} = \\ \\ \frac{15}{120} = \frac{1}{8}$

❀ Resta:

$\frac{13}{1} - \frac{5}{2} = \\ \\ \frac{2 \div 1 \times 13 - 2 \div 2 \times 5}{2} = \\ \\ \frac{26 - 5}{2} = \\ \\ \frac{21}{2} = 10 \frac{1}{2}$

❀ Suma:

$\frac{4}{3} + \frac{5}{9} = \\ \\ \frac{9 \div 3 \times 4 + 9 \div 9 \times 5}{9} = \\ \\ \frac{12 + 5}{9} = \\ \\ \frac{17}{9} = 1 \frac{8}{9}$
