{\huge{\overbrace{\underbrace{\pink{Answer}}}}}

Let the third proportional to 3.6 ,1.8 be x

Then 3.6 : 1.8 :: 1.8 : x

But, product of extremes = product of means

.°.3.6 \times x = 1.8 \times 1.8

 =  >  \frac{1.8 \times 1.8}{3.6}  \\

 =  >  \frac{18 \times 18}{36 \times 10}   =  \frac{9}{10}  = 0.9 \\

Hence, the third proportional to 3.6,1.8 is 0.9
