Question

Resolva as frações a b c d e f g h i

Answer 1

Explicação passo a passo:

a) $\frac{3}{8}$ + $\frac{5}{7}$ ---> $\frac{21+40}{56}$ = $\frac{61}{56}$

b) $\frac{2}{5}$ + $\frac{7}{6}$ ---> $\frac{12+35}{30}$ = $\frac{47}{30}$

c) $\frac{5}{9}$ - $\frac{3}{12}$ ---> $\frac{20-9}{36}$ = $\frac{11}{36}$

d) $\frac{9}{6}$ - $\frac{11}{9}$ ---> $\frac{27-22}{18}$ = $\frac{5}{18}$

e) Neste caso, temos um 1 embaixo do 3

$\frac{3}{1}$ - $\frac{5}{8}$ ---> $\frac{24-5}{8}$ = $\frac{19}{8}$

f) $\frac{-9}{1}$ - $\frac{7}{6}$ ---> $\frac{-54-7}{6}$ = $\frac{-61}{6}$

g) $\frac{-5}{1}$+ $\frac{3}{8}$ ---> $\frac{(-40)+3}{8}$ = $\frac{-37}{8}$

h) $\frac{7}{1}$ + $\frac{5}{4}$ ---> $\frac{28+5}{4}$ = $\frac{33}{4}$

i) $\frac{8}{1}$ - $\frac{3}{2}$ ---> $\frac{16-3}{2}$ = $\frac{13}{2}$
