Solve: Identifying the Redundant Term in 9:3+0:100

To solve this problem, let's break down the expression step-by-step:

• Step 1: Evaluate the division $9:3$.
  This represents the division $9 \div 3$, which results in $3$.
• Step 2: Evaluate the expression $0:100$.
  Multiplication involving zero, $0 \times 100$, results in $0$.
• Step 3: Combine the results from Steps 1 and 2 using addition.
  We add the results from Step 1 and Step 2: $3 + 0 = 3$.

Therefore, the expression $9:3 + 0:100$ simplifies to $3$.

Next, we determine which number can be replaced without changing the result of the exercise:

• The expression's result is unaffected by the term $0:100$, because multiplying by zero always gives zero, contributing nothing to the sum.
  Therefore, $100$ can be replaced without changing the overall result.

Comparing this analysis with the given choices, the correct answer is: $100$.
