Example Question #11 : How To Solve One Step Equations With Fractions In Pre Algebra
What is ?
To get rid of a fraction, we multiply by the reciprocal. So we take and multiply both sides by
:
Notice that and
cancel out, leaving us with
.
At this point, you can either plug into your calculator, or you can solve this in pieces.
We can do some manipulation to get:
, so we can plug that into
.

:
Since , we can simplify that equation to
.
Therefore, .
Example Question #11 : How To Solve One Step Equations With Fractions In Pre Algebra
What is
To get rid of the , we multiply both sides by
:
Example Question #371 : High School Math
What is ?
To solve this problem we need to reduce . Both the top and the bottom of
are divisible by
, so we can reduce it to
. Anything divided by
is itself, so
is the same as
.
Example Question #11 : How To Solve One Step Equations With Fractions In Pre Algebra
What is ?
To solve, multiply the right side:
Example Question #12 : How To Solve One Step Equations With Fractions In Pre Algebra
What is ?
To solve this problem, multiply across: .
is a prime number, so we cannot reduce further. From here, covert
into a mixed fraction:
Example Question #13 : How To Solve One Step Equations With Fractions In Pre Algebra
What is ?
To solve this problem, multiply across:
Example Question #372 : High School Math
Solve for .
Example Question #373 : High School Math
Solve for .
To solve for , we need to isolate our variable. That means that we want ONLY the
on the left side of the equation.
We want to divide by . The way you divide by a fraction is to multiply by the reciprocal. The reciprocal of
is
.
Therefore:
Since , we can ignore it.
