Question

1/2 : 0,5 + 1/4 : 0,25 + 1/8 : 0,125

Answer 1

\(\dfrac{1}{2}:0,5+\dfrac{1}{4}:0,25+\dfrac{1}{8}:0,125\)

\(=\dfrac{1}{2}\times2+\dfrac{1}{4}\times4+\dfrac{1}{8}\times8\)

\(=\dfrac{2}{2}+\dfrac{4}{4}+\dfrac{8}{8}=1+1+1=3\)

Answer 2

1/2 : 0,5 + 1/4 : 0,25 + 1/8 :0,25

đổi 1/2=0,5;1/4=0,25;1/8=0,125

=0,5:0,5+0,25:0,25+0,125:0,125

=1+1+1

=3
