Question

B- Completamos con la fracción que cumpla con la igualdad. 1/5+2/5=
3/7+.....=1
1-.....=1/4
.....-5/3=1
4/3+.....=2
2-......=5/6
​

Answer 1

Respuesta:

$\frac{1}{5} + \frac{2}{5} = \frac{3}{5}$

$\frac{3}{7 } + x = 1 \\ x = 1 - \frac{3}{7} \\ x = \frac{4}{7}$

$1 - x = \frac{1}{4} \\ 1 - \frac{1}{4} = x \\ \frac{3}{4} = x$

$x - \frac{5}{3} = 1 \\ x = 1 + \frac{5}{3} \\ x = \frac{8}{3}$

$\frac{4}{3} + x = 2 \\ x = 2 - \frac{4}{3} \\ x = \frac{6}{3} - \frac{4}{3} \\ x = \frac{2}{3}$

$2 - x = \frac{5}{6} \\ 2 - \frac{5}{6} = x \\ \frac{12}{6} - \frac{5}{6} = x \\ \frac{7}{6} = x$
