Question

como somar a fração 4/4+2/3+6....6/8÷2/3.....5+3/4+1/3 obrigado

Answer 1

a)

$\frac{4}{4} + \frac{2}{3} +6= \frac{12+8+72}{12} = \frac{92}{12} = \frac{92:4}{12:4} = \frac{23}{3}$

b)

$\frac{6}{8} : \frac{2}{3} = \frac{6}{8} . \frac{3}{2}= \frac{18}{16} = \frac{9}{8}$

c)

$5+ \frac{3}{4} + \frac{1}{3} = \frac{60+9+4}{12} = \frac{73}{12} =6 \frac{1}{12}$
