d)84/28

e)54/40


​

Answer 1

→ Cálculo :

$\\ { \large \displaystyle \sf {b) \ \frac{35}{80} = \frac{35 \div 5}{80 \div 5} = \boxed{ \red{\frac{7}{16} }}}}$

${ \large \displaystyle \sf {c) \ \frac{12}{10} = \frac{12 \div 2}{10 \div 2} = \boxed{ \red{ \: \frac{6}{5} \: }}}}$

${ \large \displaystyle \sf {d) \ \frac{84}{28} = \frac{84 \div 28}{28 \div 28} = \frac{3}{1} = \boxed{ \red{ \: 3 \: }}}}$

${ \large \displaystyle \sf {e) \ \frac{54}{40} = \frac{54 \div 2}{40 \div 2} = \boxed{ \red{ \frac{27}{20} }}}}$
