Understanding the Problem

In this problem, we are asked to convert the mixed number $-1 \frac{1}{10}$ into a decimal number. A mixed number is a combination of a whole number and a fraction. In this case, we have a negative whole number and a fraction with a denominator of 10.

The Importance of Converting Mixed Numbers to Decimal Numbers

Converting mixed numbers to decimal numbers is an essential skill in mathematics, particularly in algebra and calculus. It allows us to perform calculations and operations with mixed numbers more easily and accurately. In addition, converting mixed numbers to decimal numbers helps us to visualize and understand the concept of fractions and decimals.

Step 1: Convert the Fraction to a Decimal Number

To convert the fraction $\frac{1}{10}$ to a decimal number, we can divide the numerator (1) by the denominator (10). This gives us a decimal number of 0.1.

Step 2: Combine the Whole Number and the Decimal Number

Now that we have converted the fraction to a decimal number, we can combine it with the whole number. We have a negative whole number of -1 and a decimal number of 0.1. To combine them, we can add the decimal number to the whole number. However, since the whole number is negative, we need to subtract the decimal number from the whole number.

Step 3: Simplify the Expression

Now that we have combined the whole number and the decimal number, we can simplify the expression. We have -1 + 0.1, which can be simplified to -0.9.

Conclusion

In this problem, we have converted the mixed number $-1 \frac{1}{10}$ to a decimal number. We have followed the steps of converting the fraction to a decimal number and combining the whole number and the decimal number. The final answer is -0.9.
