=5/8.9/36=5/32

POR FAVOR ME AJUDEM!!!!!

Answer 1

0,25 +3/8 . [ ( 0,5 + 1/3 ). 2 - 0,4] =
1/4 + 3/ 8 . [ ( 1/2 + 1/ 3 ) . 2 - 2/5 ] =
1/4 + 3/ 8 . [ ( 3/6 + 2/6 ) . 2 - 2/5 ] =
1/4 + 3/ 8 . [ ( 5/ 6) . 2 - 2/5 ] =
1/4 + 3/ 8 . [ 10/ 6 - 2/5 ] =
1/4 + 3/ 8 . [ 50 /30 - 12/ 30 ] =
1/4 + 3/ 8 . [ 38 /30 ] =
1/4 + 114/ 240 =
60/ 240 + 114 / 240 =
174 / 240 =  0,725
