i don't know how to do mixed numbers with negative and positive numbers, if anyone can point me in the right direction i would be thankful!
Like this?
4 3/4 - 2 1/8 =
4 6/8 - 2 1/8 = 2 5/8

thank you! have a good night ma'am (^-^)
You're welcome. You have a good evening, too. :-)
Of course! I'd be happy to help you with mixed numbers involving negative and positive numbers.
To understand mixed numbers, we first need to understand fractions and integer operations. Let's start with some basics:
1. Fractions: A fraction is a number representing part of a whole. It has a numerator (the top number) and a denominator (the bottom number). For example, in the fraction 3/4, 3 is the numerator, and 4 is the denominator.
2. Integers: Integers are whole numbers, both positive and negative, including zero.
Now, let's move on to mixed numbers:
Mixed numbers are a combination of a whole number and a fraction. For example, 2 1/2 is a mixed number, where 2 is the whole number and 1/2 is the fractional part.
To work with mixed numbers involving negative and positive numbers, follow these steps:
Step 1: Add or subtract the whole numbers:
- If both numbers are positive or negative, perform the usual addition or subtraction. For instance, 5 + 3 or -4 - 2.
- If one number is positive and the other is negative, subtract their absolute values and keep the sign of the larger number. For example, 5 + (-3) would become 5 - 3, or -4 + 2 would become -4 - 2.
Step 2: Add or subtract the fractions (if any):
- If the fractions have the same denominator, simply add or subtract the numerators while keeping the denominator unchanged. For example, 1/4 + 3/4 or 1/3 - 2/3.
- If the fractions have different denominators, find a common denominator and convert the fractions accordingly before adding or subtracting.
Step 3: Simplify the result: If necessary, reduce the fraction to its simplest form by dividing the numerator and denominator by their greatest common divisor.
That's it! Once you have completed these steps, you will have your answer in the form of a mixed number with negative and positive numbers.
Remember to always double-check your calculations and take your time when working with mixed numbers. Practice helps to improve your proficiency in dealing with different types of calculations.
