Son restas de fracciones y necesito la respuesta de como se resuelve y los resultados ​

Answer 1

Hola!

Resolver:

1 - 4/5 =

$1 - \frac{4}{5} = \frac{1}{1} - \frac{4}{5} = \frac{1 \times 5}{1 \times 5} - \frac{4}{5} = \frac{5}{5} - \frac{4}{5} = \frac{5 - 4}{5 } \\ \frac{5 - 4}{5} = \frac{1}{4}$

1- 7/8 =

$1 - \frac{7}{8} = = \frac{1}{1} - \frac{7}{8} = \frac{1 \times 8}{1 \times 8} - \frac{7}{8} = \frac{8}{8} - \frac{7}{8} = \frac{8 - 7}{8} = \\ \frac{8 - 7}{8} = \frac{1}{8}$

1 - 7/10 =

$1 - \frac{7}{10} = \frac{1}{1} - \frac{7}{10} = \frac{1 \times 10}{1 \times1 0} - \frac{7}{10} = \frac{10}{10} = \frac{7 - 10}{10} \\ \frac{7 - 10}{7} = \frac{3}{10}$

Answer 2

Explicación paso a paso:

1. 4/5 - 1. 7/8 =. 9/5 - 15/8 = 75/40 - 72/40 = 3/40

1. 7/10 - 1. 7/8. =. 17/10 - 15/8 =. 150/80 - 135/80.

=. 15/80
