13 , 25 : 0, 5 + 13 , 25 : 0 , 25 + 13 , 25 : 0, 125
= 13 , 25 x 2 + 13 , 25 x 4 + 13 , 25 x 8
= 13 , 25 x ( 2 + 8 ) + 13 , 25 x 4
= 13 , 25 x 10 + 53
= 132 , 5 + 53
= 185 , 5

13,25 : 25 + 13,25 : 0,25 + 13,25 : 0,125
=13,25: (25+0,25+0,125)
=13,25: 25,375
= chịu :))
13,25:25+13,25:0,25+13,25:0,125
=13,25:25+13,25:4+13,25:6
=13,25:(25+4+6)
=13,25:35?????????????
