To solve the problem of dividing $1.1$ by $0.5$, let's simplify the operation by converting the decimals into whole numbers:

• Step 1: Multiply both the dividend and the divisor by $10$ to eliminate the decimal points:
  $1.1 \times 10 = 11$
  $0.5 \times 10 = 5$

• Step 2: Perform division on the whole numbers:
  $11 \div 5 = 2.2$

• Step 3: Interpret the result. We found that the answer to the division $1.1 \div 0.5 = 2.2$.

Therefore, the solution to the problem is $2.2$.

To solve the problem $0.4 \div 0.2$, we can follow these steps:

• Step 1: Convert the division of decimals into a division of whole numbers by multiplying both the dividend (0.4) and the divisor (0.2) by 10.
• Step 2: This operation results in dividing 4 by 2 (since $0.4 \times 10 = 4$ and $0.2 \times 10 = 2$).
• Step 3: Perform the division $4 \div 2$, which equals 2.

Thus, the result of dividing $0.4$ by $0.2$ is $\boxed{2}$.

To solve the problem $0.1 \div 0.02$, let's follow these steps:

• Step 2: Convert $0.1$ to $10$ and $0.02$ to $2$ by multiplication.
• Step 3: Perform the division $10 \div 2$.

Now, let's proceed with the calculations:
- When we multiply $0.1$ by 100, we get $10$. Similarly, multiplying $0.02$ by 100 gives us $2$.
- Next, we divide $10$ by $2$:
$10 \div 2 = 5$.

Therefore, the solution to the problem is $5$.

• Now, the division simplifies to $26 \div 1$.
• Dividing $26$ by $1$ gives us $26$.

Thus, the solution to the division problem $2.6 \div 0.1$ is $26$.

Step 3: Verify: Multiplying the result $2$ by $1.2$ should give us $2.4$, confirming the division is correct.

Therefore, the solution to the problem is $\boxed{2}$.

To solve the problem of dividing $0.64$ by $0.8$, we need to convert the decimals to whole numbers to simplify the process. Here's a step-by-step solution:

• Step 1: Notice both numbers are decimals. Our goal is to make them whole numbers to simplify the division.
• Step 2: The number $0.64$ can be written as $\frac{64}{100}$ and $0.8$ as $\frac{8}{10}$. To eliminate decimals, multiply both numbers by 100 (the larger factor of 10 to ensure both numbers become integers): $0.64 \times 100 = 64$ and $0.8 \times 100 = 80$.
• Step 3: Perform the division using these whole numbers: $\frac{64}{80}$.
• Step 4: Simplify $\frac{64}{80}$. The greatest common divisor of 64 and 80 is 16. Thus, dividing both the numerator and the denominator by 16, we get $\frac{64 \div 16}{80 \div 16} = \frac{4}{5}$.
• Step 5: Convert $\frac{4}{5}$ to decimal form. To do this, divide 4 by 5, which gives us $0.8$.

Therefore, the solution to the problem $0.64 \div 0.8$ is $0.8$.

• Step 1: Convert $0.3$ (the divisor) into a whole number by multiplying both $0.18$ and $0.3$ by 10.
• Step 2: Perform the division with whole numbers.

Let's perform the steps:

Step 1: Multiply both $0.18$ and $0.3$ by 10 to get:

$(0.18 \times 10) = 1.8$

$(0.3 \times 10) = 3$

Step 2: Now divide the whole numbers:

$\frac{1.8}{3} = 0.6$

Thus, the division of $0.18$ by $0.3$ results in $0.6$.

To solve the problem $1.6 \div 0.2$, we will eliminate the decimals by converting the numbers into whole numbers and performing the division.

• Step 1: Convert the decimals to whole numbers. Multiply both 1.6 and 0.2 by 10 to remove the decimal places.
  $1.6 \times 10 = 16$ and $0.2 \times 10 = 2$.
• Step 2: Perform integer division. Now divide the two whole numbers obtained:
  $16 \div 2 = 8$.
• Step 3: Verify the result. Verify by direct division using decimals:
  Perform $1.6 \div 0.2$ which is equivalent to $\frac{16}{2} = 8$.

The calculation confirms that our approach is correct, ensuring accuracy both in removing decimals and dividing.

Therefore, the solution to $1.6 \div 0.2$ is $8$.

• Step 3: Now perform the division $11 \div 2$.

Let's perform the calculation:

• Step 1: The division $11 \div 2$ is performed as follows:
• Step 2: By dividing $11$ by $2$, we note that $2$ goes into $11$ exactly $5$ times to give $10$, with a remainder of $1$.
• Step 3: Continue by considering the remainder as a decimal: $1.0 \div 2 = 0.5$ (as $2$ goes into $10$ exactly $5$ times).
• Step 4: Adding the whole and decimal parts together gives us $5 + 0.5 = 5.5$.

Therefore, the solution to the problem $1.1 \div 0.2$ is $5.5$.

To solve the division of two decimal numbers $0.49$ and $0.7$, we will follow these steps:

• Step 1: Convert the decimals to fractions. Since $0.49$ has two decimal places, it can be written as $\frac{49}{100}$. Similarly, $0.7$, which has one decimal place, can be written as $\frac{7}{10}$.
• Step 2: Set up the division of fractions: $\frac{49}{100} \div \frac{7}{10}$.
• Step 3: Recall that division by a fraction is the same as multiplication by its reciprocal. Thus, we rewrite the division as multiplication by the reciprocal of $\frac{7}{10}$:

$\frac{49}{100} \times \frac{10}{7}$.

• Step 4: Multiply the numerators and the denominators:

$\frac{49 \times 10}{100 \times 7} = \frac{490}{700}$.

• Step 5: Simplify the fraction by finding the greatest common divisor (GCD) of $490$ and $700$. The GCD is $70$.

After dividing both the numerator and the denominator by $70$, we have:

$\frac{490 \div 70}{700 \div 70} = \frac{7}{10}$.

Thus, the result of $0.49 \div 0.7$ is $\frac{7}{10}$, which is $0.7$.

Therefore, the solution to the problem is $0.7$.

Step 2: Perform the division.
Divide 109 by 25. When dividing, you get 4 as the quotient and a remainder of 9. Therefore, 109 ÷ 25 = 4.36.

Step 3: Adjust for decimal placement.
Since we initially multiplied by 10, dividing by 25 effectively places the decimal in the correct position. Thus, 10.9 ÷ 2.5 = 4.36.

Therefore, the solution to the problem is $4.36$.

• Step 1: Convert the decimals to whole numbers. Multiply both the numerator (4.4) and the denominator (1.1) by 10 to eliminate the decimal points, resulting in $44 \div 11$.
• Step 2: Perform the division $44 \div 11$. Since $44$ divided by $11$ is $4$, the quotient is 4.
• Step 3: Interpret and verify the result. Since multiplying by 10 does not affect the ratio (or quotient), the result is valid for the original problem.

Therefore, the solution to the problem $4.4 \div 1.1$ is $4$.

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

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