Number and Operations>Extending Representations of Division to Fraction Notation(TEKS.Math.6.2.E) Practice Test

$7/3$ means $3 \div 7$ because the denominator comes first.

They represent the same number because the fraction bar means divide $7$ by $3$.

$7/3$ means $7 - 3$.

The fraction bar means absolute value, so $7/3$ is always positive no matter the signs.
