What is 18 divided by 2/3?
pishuonlain [190]
Division is basically
x divided by y=x/y so
18 divided by 2/3=\frac{18}{ \frac{2}{3} }
we want the bottom number to be =1 so we multiply 2/3 by 3/2 to make it 1 (or 6/6=1), but we have to multiply the top number by 3/2 also so that we don't change the fraction and make our work useless so

\frac{18}{ \frac{2}{3} } times  \frac{ \frac{3}{2} }{ \frac{3}{2} } = \frac{ \frac{54}{2} }{ \frac{6}{6} }= \frac{27}{1}=27

the answe ris 27

What are the steps to find the value of b ?
vazorg [7]
The angles should add to 540, so
b+ (3/2)b+(b+45)+(2b-90)+90=540

First combine like terms
5.5b+45=540

Then subtract 45 from both sides
5.5b=495

Divide both sides by 5.5
b=90

Final answer: b=90
