Ya que juana tenia 23 caramelos dividelo entre el total de 2/5 a lo que da 09(7/5)
Tenían 200 caramelos
Explicación paso a paso:
Ana : x caramelos
Teresa : 3/5 x caramelos
Maria : 2/5 (x -3/5x) caramelos
Juana :23 caramelos
[tex]\frac{3}{5}x+\frac{2}{5}\left(x-\frac{3}{5}x\right)+23=\frac{7}{8}x\\\\\\\frac{3}{5}x+\left[\frac{2}{5}\left(\frac{2x}{5}\right)\right]+23\:=\:\frac{7}{8}x\\\\\\\frac{3}{5}x+\left[\frac{4x}{25}\right]+23\:=\:\frac{7}{8}x\\\\\frac{3}{5}x+\left[\frac{4x}{25}\right]=\frac{7}{8}x-23\\\\\mathrm{Restar\:}\frac{7}{8}x\mathrm{\:de\:ambos\:lados}\\\\\frac{3}{5}x+\left[\frac{4x}{25}\right]-\frac{7}{8}x=\frac{7}{8}x-23-\frac{7}{8}x\\\\[/tex]
[tex]-\frac{23x}{200}=-23\\\\\mathrm{Multiplicar\:ambos\:lados\:por\:}200\\\\200\left(-\frac{23x}{200}\right)=200\left(-23\right)\\\\-23x=-4600\\\\x=200[/tex]
