how to write -29 in a/b form
1) Negative numbers can be used in various scenarios to describe measurements or events. Two examples are:
- Temperature: Negative numbers are commonly used in measuring temperature, especially in regions that experience below zero temperatures. For instance, a temperature of -10 degrees Celsius describes a lower temperature than 0 degrees Celsius, indicating a colder condition.
- Debt or Financial Transactions: Negative numbers are used to represent debts or financial losses. For example, if someone owes $50, it can be represented as -$50, indicating a negative balance or amount owed.
2) To write a rational number in the form A/b, where A and b are integers and b is not equal to 0, you need to convert the given decimal into a fraction. Let's take the example you provided:
Example A: 0.7
To convert 0.7 into a fraction, you need to determine its decimal place value. Here, 0.7 has one decimal place, which means it can be written as 7/10 (since the decimal is in the tenths place).
Therefore, the rational number 0.7 can be written as 7/10.
