3219/1800 = 3219/ 23 x 52 x 32

We know 2, 3 and 5 are not the factors of 3219. 

So, the given rational is in its simplest form. 

∴ (2 3 × 5 2 × 3 2 ) ≠ (2m × 5n ) for some integers m, n. 

Hence, 3219/1800 is not a terminating decimal. 

3219/1800 = 1.78833333…. 

Thus, it is a repeating decimal.
