1. The problem is to multiply the numbers 2.6 and 5.2. 2. The formula for multiplication is simply $a \times b$ where $a$ and $b$ are the numbers to multiply. 3. Multiply 2.6 by 5.2: $$2.6 \times 5.2$$ 4. Multiply as if they were whole numbers: $26 \times 52 = 1352$ 5. Since 2.6 has one decimal place and 5.2 has one decimal place, the product must have two decimal places. 6. Place the decimal point two places from the right in 1352 to get 13.52. 7. Therefore, the final answer is: $$\boxed{13.52}$$
