Answer 1

Resposta:

d) $\frac{117}{20}$

e) $\frac{213}{40}$

Explicação passo-a-passo:

d) $2\frac{3}{5}+3\frac{1}{4}=\frac{13}{5}+\frac{13}{4}\\ \\\frac{52}{20}+\frac{35}{20}=\frac{117}{20}$

e)$3\frac{1}{5}+2\frac{1}{8} = \frac{16}{5} +\frac{17}{8}\\\\\frac{128}{40}+\frac{85}{40} = \frac{213}{40}$
