Solve Decimal Division: Calculate 4.4:1.1 Using Ratio Notation

To solve the problem $4.4 \div 1.1$, we will proceed with the following steps:

• 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 $4$.
