Step-by-Step Solution

To solve the given problem, we need to divide the decimal number 1.51.5 by 200200.

  • Step 1: Understand the problem setup as 1.5÷2001.5 \div 200.
  • Step 2: Perform the division.

Let's interpret 1.51.5 as the fraction 1510\frac{15}{10} to assist with division:

Rewriting the division, we have:

1.5200=1510200=152000\frac{1.5}{200} = \frac{\frac{15}{10}}{200} = \frac{15}{2000}

Step 3: Now we divide 1515 by 20002000.

First, set up the division: 15÷200015 \div 2000. This is equivalent to finding: 152000\frac{15}{2000}.

Perform the division plant normally or using a calculator:

1. Start by noting the decimal point position. 15.000÷200015.000 \div 2000 essentially. Perform one digit at a time if manual.

2. You calculate 152000=0.0075\frac{15}{2000} = 0.0075 accurately. Be critical with decimal placement!

Therefore, the quotient of dividing 1.51.5 by 200200 is 0.00750.0075.

Hence, the correct answer is 0.00750.0075, which corresponds to choice 22.

Answer

0.0075 0.0075
