Question

Which of the following measurement is the greatest?

• A. 25 cm
• B. 25 m
• C. 2500 mm
• D. 2.5 cm

Answer 1

The correct option is B 25 m

We know that,
1 m = 100 cm
1 cm = 10 mm
1 mm = $\frac{1}{10}$ = 0.1 cm

25 m = 25 $\times$ 100 cm = 2500 cm

2500 mm = $\frac{2500}{10}$ cm = 250 cm

$\therefore$ the correct order is :
$25\text{m}>2500\text{mm}>25\text{cm}>2.5\text{cm}.$
