Question

qual e a maior fração ente 1/2 3/5 7/10 e 13/20

Answer 1

$\dfrac{1}{2} \ \ \ \dfrac{3}{5} \ \ \ \dfrac{7}{10} \ \ \ \dfrac{13}{20}$

mmc(2, 5, 10, 20) = 20

$\dfrac{1}{2}=\dfrac{10}{20} \ \ \ \ \ \ \ \dfrac{3}{5}=\dfrac{12}{20} \ \ \ \ \ \ \ \dfrac{7}{10}=\dfrac{14}{20}$

$\dfrac{10}{20}<\dfrac{12}{20}<\dfrac{13}{20}<\dfrac{14}{20}$

Ou seja,

$\dfrac{1}{2}<\dfrac{3}{5}<\dfrac{13}{20}<\dfrac{7}{10}$

A maior fração é $\dfrac{7}{10}$

$\dfrac{1}{2}=0,5 \ \ \ \ \ \ \ \dfrac{3}{5}=0,6 \ \ \ \ \ \ \  \dfrac{7}{10}=0,7 \ \ \ \ \ \ \ \dfrac{13}{20}=0,65$
