Comparing Rational Forms Practice Test

The student made an error; $$\frac{3}{7} = 0.42\overline{857142}$$, not $$0.428571$$

The student's conversion is correct, but $$0.428571... < 0.43$$, so more precision is needed

The student correctly converted $$\frac{3}{7}$$ to decimal form and the comparison is valid

The reasoning is flawed because $$\frac{3}{7}$$ cannot be compared directly to $$0.42$$
