Question

{4+2[32-1/4(4/6-1/8)+2]+16}

Answer 1

4/6 - 1/8 MMC = 24
16/24 - 3/24
=13/24

32-1/4*13/24+2
32-13/96+2
34-13/96

2 [34-13/96]
68-26/96
68-13/48

16+4+68-13/48
88-13/48
88-0,27
87,73 aproximadamente

Answer 2

Oi. :)  Segue
$4+2(32- \frac{1}{4}( \frac{4}{6} - \frac{1}{8})+2)+16 \\ \\ 4+2(32- \frac{1}{4}( \frac{16-3}{24} )+2)+16 \\ \\ 4+2(32- \frac{1}{4}( \frac{13}{24} )+2)+16 \\ \\ 4+2(32- \frac{13}{96}+2)+16 \\ \\ 4+2( \frac{3072-13+192}{96})+16 \\ \\ 4+2( \frac{3251}{96})+16 \\ \\ 4+ \frac{6502}{96}+16 \\ \\ 20+ \frac{3251}{48} \\ \\ \frac{960+3251}{48} = \frac{4211}{48}$
