The difference of fractions can be found using the formula ...
a/b -c/d = (ad -bc)/(bd)
<h3>Difference</h3>
Using the given values in the formula, we have ...

Here, the difference fraction does not need to be reduced. Many calculators and spreadsheets can do this arithmetic for you.
The above formula can also be used for sums of fractions. In that case, the sign changes from minus to plus.
The answer is 3.5. Do you need me to explain or is that ok?
Fourth answer
basically the points where y=0

Answer:
x=-12
Step-by-step explanation:
Start by getting all of the x values on one side and other to the other.
1/3x-3/4x=1+4
Now simplify. Because 1/3 and 3/4 do not have the same denominator, find the least common factor between 3 and 4 (which is 12) and make the fractions have denominators of 12.
4/12x-9/12x=5
-5/12x=5
x=5*(12/-5)=60/-5=-12
x=-12
7m - 3n
m = 3, n = 2
Replace m and n with the appropriate numbers:
7(3) - 3(2)
Multiply both sides:
21 - 6
Subtract:
21-6 = 15
