Give an example of a real world situation that could be represented by the expression -1.4-2.3. Then simplify the expression and tell what the answer means in the context of the situation.
Maureen borrowed $1.40 from her dad. Then she realized she needed $2.30 more. She now is in debt 2.3 + 1.4 = $3.70.
- 1.4 + -2.3 = -3.7
Create a real word situation that could be represented using the expression
Sure! One real world situation that could be represented by the expression -1.4 - 2.3 is a person's bank account balance.
Let's say a person had a balance of -1.4 dollars in their account and they withdrew $2.3 from the account. To represent this situation using the expression, we would subtract 2.3 from -1.4.
Simplifying the expression, -1.4 - 2.3 equals -3.7. The answer -3.7 means that after withdrawing $2.3 from a bank account that had a balance of -$1.4, the person's updated account balance would be -$3.7. In this context, the negative value indicates a deficit or debt in the bank account.
A real-world situation that could be represented by the expression -1.4 - 2.3 is a person's financial liabilities.
Let's say a person has a credit card debt of $1,400 and an additional loan of $2,300. Both amounts are expressed as negative numbers because they represent money owed or liabilities. The expression -1.4 - 2.3 represents the total debt or liabilities of the person.
To simplify the expression, we add the numbers:
-1.4 + (-2.3) = -3.7
So, the simplified expression is -3.7.
In the context of the situation, the answer of -3.7 means that the person has a total debt of $3,700. The negative sign indicates that the debt is owed, so the person owes $3,700 in total.
