Division within 10 000

 
2.4  Division within 10 000

There are various methods for solving appropriate divisions operations for numbers up to 10 000
  Examples of division operation questions and solutions  
 

We put 45 small stones equally into 3 jars. Calculate the number of small stones in one jar.

Mathematical sentence: \(45\space\div\space3=\underline{\quad\quad}\)

 

 
 

METHOD

\(\;\;\;15\\ 3\overline{\smash{)}45}\\ \,\underline{-3}\downarrow\\ \;\;\,15\\ \;\underline{-15}\\ \;\;\,\,\;00 \)

Divide tens

4 tens\(\div\) 3 = 1 tens remainder 1 tens

 

Change 1 tens to 10 ones.

10 sa \(+\) 5 sa = 15 sa

Divide ones

15 ones \(\div\) 3 = 5 ones

 
  So, \(45\space\div\space3=\underline{15}\)
