Example Question #1 : Multiplying And Dividing Fractions
Solve the following equation to find .
The first step in solving this equation is to add the fractions, giving us:
To solve for , we need to divide both sides by .
Remember: When we divide a number by a fraction, we "switch" (find the reciprocal) of the fraction and mulitply it to the number.
The right side of the equation cancels out leaving alone:
Notice: Both the numerator and denominator are divisble by so we can simplify this further.
Example Question #1 : Multiplying And Dividing Fractions
Simplify .
The problem can be made easier by first simplifying each fraction: and .
This brings our new problem to .
Now, the numerators are multiplied by each other then the denomenators are multiplied by each other: .
Example Question #1 : Multiplying And Dividing Fractions
Simplify .
To solve, we must turn the division problem into a multiplication problem by "flipping" the second fraction (dividing by a fraction is the same as multiplying by its reciprocal):
.
Then, we multiply the numerators followed by the denomenators:
.
Lastly, the fraction must be simplified by a factor of 3:
, which gives us our final answer.
