Question

$$2.16/3.6$$

Answer

0.6

Solution


Shift the decimals of both 2.16 and 3.6 to the right by 1 decimal place. (This is needed to convert 3.6 to 36, since long division must divide by a whole number.)
\[21.6\div 36\]
Use the algorithm method.
.6
36|21.6
21.6
Therefore, \(2.16\div 3.6=0.6\).
\[0.6\]
