Answer:

Hope 292.5 is right.

Step-by-step explanation:

First thing, multiply the triangles base and height which will give you 143 then divide it by two which is 71.5. Then to the parallelogram which is base times height which is 117. Moving on to the trapezoid, meanin one-hal times height times first base plus second base giving you 104. Finally, add'em up, giving you a total of 292.5.

Simplify negative 3 over 2 / 9 over 6
Temka [501]
\mathrm{Simplify} -\frac{3}2\div\frac{9}6.

Dividing by a fraction is the same as multiplying by its reciprocal. (flipped version)

-\frac{3}2\div\frac{9}6=-\frac{3}2\times\frac{6}{9}

6 and 9 are both divisible by 3, so we can simplify 6/9 = 2/3.

-\frac{3}2\times\frac{2}3

We can multiply across right now, but we might as well cross cancel.
Look at the numbers diagonal from one another...-3 and 3 are both divisible by 3, so we can change them to -1 and 1...2 and 2 are both divisible by 2, so we can change them to 1 and 1...

-\frac{1}1\times\frac{1}1

Any fraction over 1 can just be expressed as a whole number.

-1\times1

Our final answer...-\frac{3}2\div\frac{9}6=\boxed{-1}

If you were to multiply across, (maybe you don't like cross cancelling, idk?) you'd get the same answer, of course.

-\frac{3}2\times\frac{2}3=-\frac{6}6=\boxed{-1}
