I hope this helps. Thanks for asking.
Are you sure that is 3rd grade? I am a 4th grader and I don't know any thing about it.
ps. When you are done with homework go to clubpegiun. It is really cool.
When asked to use compatible numbers, there are a few steps you can follow:
1. Determine the operation: Find out if the problem requires addition, subtraction, multiplication, or division. This will help you understand how to use compatible numbers.
2. Identify compatible numbers: Compatible numbers are usually close to the given numbers and make the math easier to calculate mentally. Look for numbers that are easy to work with, such as multiples of 10, 100, or fractions like 1/2 or 1/4.
3. Round the numbers: If the given numbers are complicated or involve decimals, round them to the nearest compatible number. For example, if you have the numbers 238 and 16, you could round them to 240 and 20, respectively, which are more manageable.
4. Perform the calculation: Use the compatible numbers to perform mental math. For addition and subtraction, add or subtract the compatible numbers and adjust the answer based on the rounding. For multiplication and division, use the rounded compatible numbers to estimate the answer quickly.
5. Adjust the answer: Remember that using compatible numbers is an estimation technique, so your answer may not be exact. Compare your estimated answer with the original numbers to see if it's reasonable. If needed, you can use the accurate answer from a calculator or further refine your estimate.
By using compatible numbers, you can simplify mathematical calculations and make them easier to solve mentally while still getting a reasonable estimate.
