The correct expanded form of 67.45 is:
(6×10) + (7×1) + (4×0.1) + (5×0.01)
This can also be written as:
(6×10) + (7×1) + (4×(1/10)) + (5×(1/100))
From the responses provided, no option exactly matches the correct expanded form. However, if we interpret "110" as 10 and "1100" as 100 instead of 1000 and 10000, the option that closely resembles the correct interpretation is:
(6×10) + (7×1) + (4×100) + (5×1000), though that would not be accurate either since 4 isn't associated with 100.
Therefore, it seems there might be a misunderstanding in the options listed. Based solely on numerical expansion, the closest answer structure to what would be correct is not fully listed.
