Question

find the missing number: if 5 × 6 = 30, then 5 × __ = 300.

Explanation:

Step1: Analyze the relationship between products

We know that \(5\times6 = 30\), and we need to find \(x\) such that \(5\times x=300\). Notice that \(300\) is \(30\times10\).

Step2: Apply the multiplication property

Since the first factor (5) remains the same, and the product is multiplied by 10 (from 30 to 300), the second factor should also be multiplied by 10. So \(6\times10 = 60\). We can also solve it by the formula \(x=\frac{300}{5}\), and \(\frac{300}{5}=60\).

Answer:

60
