Understanding the Problem: 65 ÷ 0.5
Before diving into the solution, let’s break down the problem. We’re dividing 65 by 0.5, which is a decimal. Decimals can make division seem complex, but with the right approach, it becomes straightforward. (decimal division, math basics)
Step-by-Step Solution to 65 ÷ 0.5
Step 1: Convert the Decimal to a Whole Number
To simplify the division, convert 0.5 into a fraction. 0.5 is equivalent to 1⁄2. Now, the problem becomes 65 ÷ (1⁄2). (decimal to fraction, division steps)
Step 2: Apply the Division Rule for Fractions
When dividing by a fraction, multiply by its reciprocal. The reciprocal of 1⁄2 is 2⁄1. So, 65 ÷ (1⁄2) becomes 65 × 2. (fraction division, reciprocal rule)
Step 3: Perform the Multiplication
Multiply 65 by 2:
65 × 2 = 130.
Therefore, 65 ÷ 0.5 = 130. (multiplication, final answer)
💡 Note: Always double-check your multiplication to ensure accuracy.
