Answer:
Step-by-step explanation:
Look at the picture.
ΔADC and ΔCDB are similar (AA). Therefore the sides are in proportion:
We have:
Substitute:
<em>cross multiply</em>
<em>divide both sides by 12</em>
I not no who you do this man
(-2/3)*(-2 1/4)*(3/4) Convert the mixed fraction to improper fraction.
(-2/3)*(-9/4)*(3/4) Then you multiply the numerators with numerators and denominators with denominators
(-2*-9*3) negative times negative is positive, so the negative sign is gone
-------------
(3*4*4*) The lines (-----) is the line of the fraction
54/48 This is the product of this multiplication, now you need to simplify
by reducing the numbers of the fraction
9/8 And that would be the answer
