Example Question #7 : How To Subtract Complex Fractions
Solve for .
Find the least common denominator which is . Then multiply the left fraction numerator by
and multiply the right numerator by
in order to make each fraction share the common denominator.
Distribute and be careful of the negative sign.
Simplify the numerator and cross multiply. Because there is an absolute value bar, we need to split this expression into two different equations.
Equation one:
By inspection, these values pass and don't violate the fractions being undefined.
Equation two:
This answer is imaginary and not in the choices leaving
as the answers.
Example Question #1 : How To Divide Complex Fractions
Keep in mind that the main fraction line just means "divide."
So then,
Now, divide this like any other fraction.
Example Question #151 : Number Concepts And Operations
Remember that the main line in the fraction means "divide."
Then,
Now, divide this like you would divide any other fraction.
Example Question #152 : Number Concepts And Operations
Remember that the main line in the fraction means "divide."
Now,
Divide these two fractions.
Example Question #153 : Number Concepts And Operations
The main fraction line means "divide."
Rewrite the complex fraction:
Divide these fractions.
Example Question #154 : Number Concepts And Operations
The main fraction line means "divide."
Rewrite the complex fractions as thus:
Now, divide these two fractions.
Example Question #155 : Number Concepts And Operations
The main fraction line means "divide." Rewrite the complex fraction as thus:
Divide these two fractions.
Example Question #156 : Number Concepts And Operations
The main line in a fraction means "divide." Rewrite the complex fraction as thus:
Now, divide the fractions.
Example Question #157 : Number Concepts And Operations
The main line in a fraction means "divide." Rewrite the complex fraction as thus:
Now, divide the fractions.
Example Question #158 : Number Concepts And Operations
The main line in a fraction means "divide." Rewrite the complex fraction as thus:
Now, divide these fractions.
