Answer 2

$\color{fuchsia}{\qquad\sf{ \: \: \: \: \: \: \: \: Solution}}$

$\sf \small{(1) \: Thousands \:(6554 - 677) }$

$\dashrightarrow \sf \small{7000 - 1000 = 6000}$

$\sf \small{(2) \:Hundreds \:(6554 - 677) }$

$\dashrightarrow \sf \small{6600 - 700 = 5900}$

$\sf \small{(3) \: Greatest \: Places \:(6554 - 677) }$

$\dashrightarrow \sf \small{7000 - 700 = 6300}$

Estimation to their hundreds is most reasonable.
