Please someone help me on 7th grade unit 4 lesson 3 (adding and subtracting mixed numbers)!!!
google can provide lots of examples for you.
Or post a few questions here.
Think -- common denominator
No one knows the answers!? I need help! :( :( :(
BRUHHHHHHHHHHHHHHHHHHH I NEED ANSWERSSSSSSSSSSSSS IMMA GONNA FAIL AND GET GROUNDED!
bruh
bruh
help pls idots
How you gone ask for help then call us a idiot that's why you didn't get any help
Of course, I can help you with that! Let's go through the steps to add and subtract mixed numbers.
Step 1: Understand the problem
Read the problem carefully to understand what it is asking you to do. Identify whether you need to add or subtract the mixed numbers.
Step 2: Convert the mixed numbers to improper fractions
To perform addition or subtraction, it's easier to work with improper fractions. To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator. Write this value over the denominator.
Step 3: Find a common denominator
If the fractions have different denominators, you need to find a common denominator. The common denominator is the least common multiple (LCM) of the two denominators.
Step 4: Convert the fractions to have the common denominator
To do this, multiply the numerator and denominator of each fraction by the same value that makes the denominators equivalent to the LCM (common denominator).
Step 5: Perform the operation (addition or subtraction)
If you are adding the fractions, add the numerators and write the result over the common denominator.
If you are subtracting the fractions, subtract the numerators and write the result over the common denominator.
Step 6: Simplify the fraction, if needed
If the fraction can be simplified, divide the numerator and denominator by their greatest common divisor (GCD) to get the simplest form of the fraction.
Step 7: Write the answer in mixed number form, if necessary
If the problem asks for the answer in mixed number form, divide the numerator by the denominator. The quotient will be the whole number, and the remainder will be the new numerator.
Step 8: Check your answer
Before you submit your answer, double-check your work to make sure you haven't made any mistakes.
If you can provide a specific problem from your lesson, I'll be happy to guide you through solving it step-by-step!
