Answer 1

Răspuns:

Explicație pas cu pas:

d)5/7+(1*7+4)/7+2/7=18/7

e)(4*8+5)/8-5/8+1/8=33/8

f)8/9-4/9+(1*9+4)/4=17/9

Answer 2

Răspuns:

d)

$\frac{8}{9} - \frac{4}{9} + 1 \frac{4}{9} = \frac{4}{9} + \frac{13}{9} = \frac{17}{9} = 1 \frac{8}{9}$

e)

$\frac{5}{7} +1 \frac{4}{7} + \frac{2}{7} = \frac{5}{7} + \frac{11}{7} + \frac{2}{7} = \frac{18}{7} = 2 \frac{4}{7}$

f)

$4 \frac{5}{8} - \frac{5}{8} + \frac{1}{8} = \frac{37}{8} - \frac{5}{8} + \frac{1}{8} = \frac{32}{8} + \frac{1}{8} = \frac{33}{8} = 4 \frac{1}{8}$
