RhondaSommer (rhondasommer):
4*9 = 36
OpenStudy (phi):
The simplest way to multiply fractions is multiply
top times top
and bottom times bottom
but that does not get you the lowest form.
Even better is to simplify the top and bottom first before multiplying
RhondaSommer (rhondasommer):
15=36 and then simplify
OpenStudy (anonymous):
Cross multiply:
3 * 9 = 4 * 5
Simplifying
3 * 9 = 4 * 5
Multiply 3 * 9
27 = 4 * 5
Multiply 4 * 5
27 = 20
Solving
27 = 20
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
OpenStudy (phi):
notice you have a 3 "up top" and a 9 below
I would divide both by 3 to get 1 up top and 3 down below
\[ \frac{\cancel{3}1}{4}\cdot \frac{5}{\cancel{9}3} \]
now multiply top times top and bottom times bottom
