Mixed number: 1 5/10

A mixed number is a number that consists of a whole number and a fraction. In the case of 1 5/10, the whole number is 1 and the fraction is 5/10.

To convert a mixed number to a decimal, we can follow these steps:

1. Convert the mixed number to an improper fraction. An improper fraction is a fraction where the numerator is greater than or equal to the denominator. To convert a mixed number to an improper fraction, we can multiply the whole number by the denominator and then add the numerator. In the case of 1 5/10, we have: ``` 1 5/10 = (1 * 10) + 5/10 = 15/10 ```
2. Divide the numerator by the denominator. The result of this division is the decimal equivalent of the mixed number. In the case of 15/10, we have: ``` 15 ÷ 10 = 1.5 ```
3. The result is the decimal equivalent of the mixed number. Therefore, 1 5/10 as a decimal is 1.5.

Convert to improper fraction: 15/10

To convert a mixed number to an improper fraction, we need to multiply the whole number by the denominator and then add the numerator. The result is a fraction where the numerator is greater than or equal to the denominator.

• Multiply the whole number by the denominator. In the case of 1 5/10, the whole number is 1 and the denominator is 10. So, we have: ``` 1 * 10 = 10 ```
• Add the numerator. The numerator of the mixed number is 5. So, we have: ``` 10 + 5 = 15 ```
• The result is the numerator of the improper fraction. The denominator of the improper fraction is the same as the denominator of the mixed number. So, the improper fraction is: ``` 15/10 ```
• The improper fraction 15/10 is equivalent to the mixed number 1 5/10. This means that they represent the same value.

Converting mixed numbers to improper fractions is a useful skill in mathematics. Improper fractions are often used in algebra and calculus. They can also be used to simplify calculations.

Divide numerator by denominator

To convert an improper fraction to a decimal, we need to divide the numerator by the denominator. The result of this division is the decimal equivalent of the fraction.

• Set up the division problem. The numerator of the fraction is the dividend, and the denominator of the fraction is the divisor. In the case of 15/10, we have: ``` 15 ÷ 10 ```
• Perform the division. We can perform the division using long division or a calculator. In this case, we can perform the division mentally: ``` 15 ÷ 10 = 1.5 ```
• The result of the division is the decimal equivalent of the fraction. Therefore, 15/10 as a decimal is 1.5.
• We can also check our answer by multiplying the decimal by the denominator and seeing if we get the numerator. In this case, we have: ``` 1.5 * 10 = 15 ```

  Since we get the numerator, we know that our answer is correct.

Dividing the numerator by the denominator is a fundamental operation in mathematics. It is used to convert fractions to decimals, to simplify algebraic expressions, and to solve equations.

Result: 1.5

When we divide the numerator (15) by the denominator (10) of the improper fraction 15/10, we get the result 1.5. This means that 1 5/10 as a decimal is 1.5.

The decimal 1.5 represents the value of the mixed number 1 5/10. It is a non-terminating decimal, which means that it has an infinite number of digits after the decimal point. However, we can round it to any desired number of decimal places. For example, we can round 1.5 to two decimal places to get 1.50, or we can round it to three decimal places to get 1.500.

Decimals are often used in everyday life. For example, we use decimals to represent money, measurements, and percentages. Decimals are also used in science, engineering, and mathematics.
