Answer:

$\frac{5.151}{5151} = \frac{5.151 \times 1000}{5151 \times 1000} = \frac{5151}{5151 \times 1000} = \frac{1}{1000} = 0.001$

$\frac{5151}{5.151} = \frac{5151 \times 1000}{5.151 \times 1000} = \frac{5151 \times 1000}{5151} = 1000$

$\frac{5.151}{515.1} = \frac{5.151 \times 1000}{515.1 \times 1000} = \frac{5151}{5151 \times 100} = \frac{1}{100} = 0.01$
