Solve Decimal Division: 15.5 ÷ 0.5 Using Standard Method

To solve this problem, we will follow these steps:

• Step 1: Remove the decimals by multiplying both the dividend and the divisor by the same power of 10.
• Step 2: Perform the division on the resulting whole numbers.
• Step 3: Simplify and verify the result against the multiple-choice options.

Now, let's work through the solution:

Step 1: Multiply both 15.5 and 0.5 by 10 to eliminate the decimals.
$15.5 \times 10 = 155$
$0.5 \times 10 = 5$

Step 2: Divide the resulting whole numbers:
$155 \div 5 = 31$

Step 3: We check the result against the choices. The result $31$ corresponds to choice 1.

Therefore, the solution to the problem is $31$.
