Question

6,7:25%+6,7:0,125-6,7 nhân2

Answer 1

\(6,7:25\%+6,7:0,125-6,7\times2\)
\(=6,7\times4+6,7\times8-6,7\times2\)
\(=6,7\times\left(4+8-2\right)\)
\(=6,7\times10\)
\(=67\)

Answer 2

\(6,7:25\%+6,7:0,125-6,7\cdot2\)

\(=6,7:0,25+6,7:0,125-6,7\cdot2\)

\(=6,7\cdot4+6,7\cdot8-6,7\cdot2\\ =6,7\cdot\left(4+8-2\right)\\ =6,7\cdot10\\ =67\)
