45 mm = 4.50 cm
45 cm
Both measurements are equivalent; 45 cm is equal to 450 mm since 1 cm equals 10 mm. Therefore, 45 cm is not bigger than 450 mm; they represent the same length.
45 mm Algebraic Steps / Dimensional Analysis Formula 4.5 cm*10 mm 1 cm=45 mm
45 mm 1 cm = 10 mm 1 mm = 0.1 cm
45 mm = 4.5 cm
457 millimetres
To compare 60 mm to 45 cm using the ratio 43, we first need to convert both measurements to the same unit. Converting 45 cm to mm gives us 450 mm. Now we can express the ratio of 60 mm to 450 mm, which simplifies to 1:7.5. The ratio 43 does not accurately represent the comparison between 60 mm and 45 cm.
62mm
1mm = 0.1cm 45mm = 4.5cm
45mm because 1 cm= 10mm so 40mm= 4cm and there's 45mm there which= 4,5cm.... :)
