Question

$$\frac{ 3.99 }{ 2.66 }$$

Answer

Solution


Shift the decimals of both 3.99 and 2.66 to the right by 2 decimal places. (This is needed to convert 2.66 to 266, since long division must divide by a whole number.)
\[399\div 266\]
Use the algorithm method.

Therefore, \(3.99\div 2.66=1.5\).
