You don't need "models and equations"; if the denominator is the same, just subtract the numerators.

Why do you needto find the LCM?
Finding the LCM will help you when you need to add and subtract fractions.
Why is finding the least common multiple important?
It will help when you are trying to add and subtract fractions.
Why should you find a LCM?
Finding an LCM will help when you want to add and subtract fractions.
How do you use prime factorization to subtract fractions in math?
Finding the prime factorizations of the denominators will help you find the least common denominator. Converting to equivalent fractions with like denominators will allow you to subtract them successfully.
How does finding the gcf help you solve real world problems?
Finding the LCM will help you add and subtract fractions. Finding the GCF will help you reduce fractions.
Why is it important to find the LCM of 2 numbers?
It will help when you want to add and subtract unlike fractions.
What is least common multiple or LCM?
The LCM is used to help you add or subtract fractions with different denominators.
Why find factor?
Finding factors is the first step in finding the GCF and the LCM. They will help you to reduce fractions, or add and subtract them.
How does multiplying fractions help solve math problems?
It depends on the specific problem. If you have an equation that involves fractions, quite often you'll need to multiply them.
What are the rules of the dissimilar fractions?
I assume you mean, with different denominators. If you want to add the fractions, subtract them, or compare them (determine which one is greater), you have to convert them to similar fractions (fractions with the same denominator) first. Converting to similar fractions is not necessary, and usually doesn't even help, if you want to multiply or divide fractions.
What is an equation you can get 24 with by using the number 6 4 and 3 no exponents may be used you may only add subtract multiply or divide please help?
Quadratic equation
How can you use equivalent fractions to help you add and subtract fractions with unlike denominators?
Change each fraction to an equivalent fraction with the same denominator. 3/8+5/12= 9/24+10/24=19/24
