Evaluate each expression. 0/7

검증된 단계별 안내
1
Identify the expression given: \(\frac{0}{7}\).
Recall the rule for division involving zero: zero divided by any nonzero number is zero.
Since the denominator is 7, which is not zero, the division is defined.
Therefore, the value of \(\frac{0}{7}\) is 0.
No further simplification is needed because the expression is already in simplest form.
