Lab- Calculate Relative Uncertainty, How many sig figs?

[ChiralWaltz]

Homework Statement

Calculate the relative uncertainty in the mass
mass (M) = 1.0 grams

Homework Equations

$\frac{\delta M}{M}$

The Attempt at a Solution

$$\delta M = \pm0.05g$$
$$\frac {0.05g}{1.0g} = 0.05$$

or
$$\frac {0.05g}{1.0g} = 0.050$$

Which one has the appropriate amount of sig figs?

thanks for your help :)

The units cancel when dividing grams by grams !
