\(\dfrac{555}{1110};\dfrac{333}{444};\dfrac{444}{555};\dfrac{118}{119};\dfrac{119}{120}\)
\(\dfrac{444}{555}\) = \(\dfrac{444:111}{555:111}\) = \(\dfrac{4}{5}\) = 1 - \(\dfrac{1}{5}\)
\(\dfrac{333}{444}\) = \(\dfrac{333:111}{444:111}\) = \(\dfrac{3}{4}\) = 1 - \(\dfrac{1}{4}\)
\(\dfrac{118}{119}\) = 1 - \(\dfrac{1}{119}\)
\(\dfrac{119}{120}\) = 1 - \(\dfrac{1}{120}\)
\(\dfrac{555}{1110}\) = \(\dfrac{555:555}{1110:555}\) = \(\dfrac{1}{2}\) = 1 - \(\dfrac{1}{2}\)
Vì : \(\dfrac{1}{2}>\dfrac{1}{3}>\dfrac{1}{4}>\) \(\dfrac{1}{119}\) > \(\dfrac{1}{120}\)
nên \(\dfrac{555}{1110}>\dfrac{333}{444}>\)\(\dfrac{444}{555}\) > \(\dfrac{118}{119}\) > \(\dfrac{119}{120}\)
Vậy Các phân số đã cho được sắp xếp theo thứ tự từ bé đến lớn là:
\(\dfrac{555}{1110}\); \(\dfrac{333}{444}\); \(\dfrac{444}{555}\); \(\dfrac{118}{119}\); \(\dfrac{119}{120}\)

=444:154
=\(\frac{222}{77}\)
444/22 x 7
= 222/11 x 7
= 1554/11
