Question

$$180000/4.5$$

Answer

40000

Solution


Shift the decimals of both 180000 and 4.5 to the right by 1 decimal place. (This is needed to convert 4.5 to 45, since long division must divide by a whole number.)
\[1800000\div 45\]
Use the algorithm method.
40000
45|1800000
180
0000
Therefore, \(180000\div 4.5=40000\).
\[40000\]
