Question

A worm travels 1250 millimeters.how many meters did the worm travel?

Answer 1

$m-meter\\mm-millimeter\\1m=1,000mm\to1mm=0.001m\\------------------\\\\1250mm=(1250\cdot0.001)m=1.250m=\boxed{1.25m}$

Answer 2

we know that

$1\ meter=1,000\ millimeters$

so

by proportion

$\frac{1}{1,000}\frac{m}{mm} =\frac{x}{1,250}\frac{m}{mm} \\ \\1,000*x=1,250\\ \\x=1,250/1,000\\ \\x=1.25\ m$

therefore

the answer is

$1.25\ m$
