Question

quero aprender sobre fração ?
$\frac{1}{14} + \frac{3}{14}$
$\frac{7}{20} + \frac{5}{20}$
$\frac{8}{15} - \frac{2}{15}$
$\frac{9}{16} - \frac{5}{16}$
$\frac{6}{10} \times \frac{4}{5}$
$\frac{7}{12} \times \frac{3}{8}$
​

Answer 1

(1 + 3)/14 = 4/14 = 2/7

(7 +5)/20 = 12/20 = 3/5

(8 -2)/15 = 6/15 = 2/5

(9 -5)/16 = 4/16 = 1/4

(6 * 4)/(10 *5) = 24/50 = 12/25

(7 * 3)/(8 * 12) = 7/(8 * 4) = 7/32
