gente me ajudem eu iria agradecer!!!!​

Answer 1

Resposta:

a)2+ 5/3

$\frac{2}{1} + \frac{5}{3} = \frac{6}{3} + \frac{5}{3} = \frac{11}{3}$

b)7+ 1/2

$\frac{7}{1} + \frac{1}{2} = \frac{14}{2} + \frac{1}{2} = \frac{15}{2}$

c)3/5+4

$\frac{3}{5} + \frac{4}{1} = \frac{3}{5} + \frac{20}{5} = \frac{23}{5}$

d)2 1/2+3/5

$2 \frac{1}{2} + \frac{3}{5} = \frac{5}{2} + \frac{3}{5} = \frac{25}{10} + \frac{6}{10} = \frac{31}{10}$

e)4/5+3 1/4

$\frac{4}{5} + 3 \frac{1}{4} = \frac{4}{5} + \frac{13}{4} = \frac{16}{20} + \frac{65}{20} = \frac{81}{20}$
