How to Solve a Adding Rational Numbers Word Problem
Problem: A submarine is at a depth of -250 meters and it descends another 130 meters. What is its new depth?
Time needed: 2 minutes
Learn how to solve a math problem involving the addition of rational numbers in a real-world context.
- Understand the Problem
Identify the initial depth and the additional descent. In this case, the submarine starts at -250 meters and descends another 130 meters.
- Set up the Equation
Write the equation as Depth = Initial depth + Additional descent. Substitute the values: Depth = -250 + (-130).
- Perform the Addition
Add the absolute values of the numbers (250 + 130 = 380) and apply the negative sign since both numbers are negative. The result is -380.
- State the Final Answer
The new depth of the submarine is -380 meters.
Frequently Asked Questions (FAQs)
What are rational numbers, and why is adding them important?
Numbers with fractional expressions where the numerator and denominator are integers are called rational numbers, and the denominator isn’t zero. They include integers, fractions, and terminating or repeating decimals.
What are the rules for adding rational numbers?
The rule for adding rational numbers depends on their signs:
– If both numbers have the same sign, add their absolute values and keep the sign.
– If the numbers have different signs, subtract the smaller absolute value from the larger absolute value and keep the sign of the larger number.
How do you add rational numbers with different signs?
To add rational numbers with different signs:
1. Subtract the smaller absolute value from the larger absolute value.
2. Keep the sign of the number with the larger absolute value.
For example, adding -7 and 4 involves finding the difference: |-7| – |4| = 3, and since -7 has the larger absolute value, the result is -3.
How do you add rational numbers?
To add rational numbers:
1. Make sure the numbers are in a common form (fractions, decimals, or integers).
2. For fractions, find a common denominator and then add the numerators.
3. For decimals, align the decimal points and add.
Apply the sign rules for adding numbers: same signs add, different signs subtract.
How do you add rationales?
Adding rationals involves ensuring they are incompatible forms and using basic arithmetic rules:
– For fractions, find a common denominator and combine the numerators.
– For decimals, align decimal points and add.
– For integers, follow the sign rules for addition and subtraction.
How do you add rational numbers between two numbers?
To add rational numbers between two numbers:
1. Convert the two numbers into their rational forms (e.g., fractions or decimals).
2. Add the numbers using the appropriate rules:
– For fractions, find a common denominator before adding.
– For decimals, align decimal points for easier addition.
3. Verify that the result falls between the original two numbers if required.
What skills do students learn from adding rational numbers worksheets?
Students gain several skills from adding rational numbers worksheets, such as:
– Understanding and adding fractions, decimals, and integers.
– Developing critical thinking and problem-solving abilities.
– Applying math to real-world scenarios, like calculating net changes or balancing values.
– Enhancing mathematical accuracy and preparing for advanced topics like algebra.
