Question

Que fraccion sumada con 1/4y 5/2 de como resultado 17/4

Answer 1

$\frac{1}{4} + \frac{5}{2} = \frac{1 + 10}{4} = \frac{11}{4}$

$\frac{17}{4} - \frac{11}{4} = \frac{6}{4} Simplificando = \frac{2}{3}$

Rspt : 

$\frac{6}{4} o sinos \frac{2}{3}$

Comprobacion :

$\frac{6}{4} + \frac{1}{4} + \frac{5}{4}$

$\frac{6}{4} + \frac{1}{4} + \frac{10}{4}$

$\frac{17}{4}$

Answer 2

Solución:

Fracción buscada:  x/y

Entonces:

$\dfrac{x}{y} + \dfrac{1}{4} + \dfrac{5}{2} = \dfrac{17}{4} \\ \\ \dfrac{x}{y}+ \dfrac{2+20}{8} = \dfrac{17}{4} \\ \\ \dfrac{x}{y}+ \dfrac{22}{8}= \dfrac{17}{4} \\ \\ \dfrac{x}{y} + \dfrac{11}{4} = \dfrac{17}{4} \\ \\ \dfrac{x}{y} = \dfrac{17}{4} - \dfrac{11}{4} \\ \\ \dfrac{x}{y} = \dfrac{17-11}{4} \\ \\ \dfrac{x}{y} = \dfrac{6}{4} \\ \\ \dfrac{x}{y} = \dfrac{3}{2}$

RTA:

La fracción buscada es 3/2
