( ghi lời giải chi tiết hộ mik nha)

 

Answer 1

= 0,54 + 0,24 + 0,12 + 0,1 

= 1

Answer 2

\(\dfrac{27}{50}+\dfrac{24}{100}+0,12+10\%\)
\(=\dfrac{27}{50}+\dfrac{12}{50}+\dfrac{6}{50}+\dfrac{5}{50}\)
\(=\dfrac{50}{50}=1\)

Answer 3

`27/50+24/100+0,12+10%`

`=27/50+6/25+3/25+1/10`

`=(27/50+1/10)+(6/25+3/25)`

`=(27/50+5/50)+9/25`

`=32/50+9/25`

`=16/25+9/25`

`=25/25=1`
