Question

2/5-1/4+7/2-4/10
Doy 100 puntos y corona al que me la responda

Answer 1

Respuesta:

$( \frac{2}{5} - \frac{1}{4} )+ (\frac{7}{2} - \frac{4}{10} ) \\ (\frac{2 \times 4 - 5 \times 1}{5 \times 4} ) + ( \frac{10 \times 7 - 4 \times 2}{10 \times 2} ) \\ ( \frac{8 - 5}{20} ) + ( \frac{70 - 8}{20} ) \\ \frac{3}{20} + \frac{62}{20} \\ \frac{65}{20} = \frac{13}{4}$

Answer 2

Respuesta:

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\blue{\boxed{\boxed{\red{¡ʜ}\blue{ᴏ}\purple{ʟ}\orange{ᴀ!}}}}$

$\bf\green{\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\: Resolvemos:}$

$\bf \frac{2}{5} - \frac{1}{4} + \frac{7}{2} - \frac{4}{10}$

$\bf \frac{2}{5} - \frac{1}{4} + \frac{7}{2} - \frac{2}{5}$

$\bf0 - \frac{1}{4} + \frac{7}{2}$

$\bf - \frac{1}{4} + \frac{7}{2}$

$\bf \frac{ - 1 + 14}{4}$

$\boxed{ \bf \frac{13}{4} }$
