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

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