Answer 1

Respuesta:

En fracción:

$?= \frac{11}{10}$

En decimal:

$?= 1,1$

Explicación paso a paso:

Resolución:

$\frac{7}{8} + \frac{?}{10} = 0,985$

$\frac{7}{8} + \frac{?}{10} = \frac{985}{1000}$

$\frac{7}{8} + \frac{?}{10} = \frac{197}{200}$

$\frac{7(25)}{8(25)} + \frac{?(20)}{10(20)} = \frac{197}{200}$

$\frac{175}{200} + \frac{?(20)}{200} = \frac{197}{200}$

$175 + ?(20) = 197$

$?(20) = 197 - 175$

$?(20) = 22$

$?= \frac{22}{20}$

$?= \frac{11}{10}$
