Question

$$2.24/22.4$$

Answer

0.1

Solution


Shift the decimals of both 2.24 and 22.4 to the right by 1 decimal place. (This is needed to convert 22.4 to 224, since long division must divide by a whole number.)
\[22.4\div 224\]
Use the algorithm method.
.1
224|22.4
22.4
Therefore, \(2.24\div 22.4=0.1\).
\[0.1\]
