How do you subtract fractions with different denominators?
2 answers:
Answer:
When solving fractions with different denominators, you first need to make the denominators the same.
Example:
-
You need to make sure the denominators are the same.
Can 2 get multiply by something and will be 4?
The answer is yes, if you multiply 2 by 2, it will change the 2 to 4. You have to multiply the equation by
(which is also equivalent to 1) and which change the equation to
.
And now you can subtract because the denominators are the same.
Hope this helps!

Using it's concept, the rate of change between point C and point D is of 2.
<h3>What is the average rate of change of a function?</h3>The average rate of change of a function is given by the <u>change in the output divided by the change in the input</u>. Hence, over an interval [a,b], the rate is given as follows:
Considering the points of the given linear function, we have that:
- Point C: f(1) = 2.
- Point D: f(2) = 4.
Hence the rate of change between point C and point D is given by:
r = (4 - 2)/(2 - 1) = 2.
