nececito ayuda en esta tares porfa​ es de matemáticas me equivoque y puse quimica

Answer 1

Explicación:

$\frac{9}{4} + \frac{2}{3} = \frac{(12 \div 4) \times 9 + (12 \div 3) \times 2}{12} = \frac{(3 \times 9) + (4 \times 2)}{12} = \frac{27 + 8}{12} = \frac{35}{12}$

$\frac{12}{5} - \frac{7}{10} = \frac{(10 \div 5) \times 12 - (10 \div 10) \times 7}{10} = \frac{(2 \times 12) - (1 \times 7)}{10} = \frac{24 - 7}{10} = \frac{17}{10}$
