Dividing Whole Numbers by Unit Fractions

Let's find the quotient of: 
 
3  ÷
1
4

 

First of all, make a model of three wholes.

 

1 a
 

Divide each whole into 4 equal parts and label each part. Each part will be 
1
4
.

 

1 b
 

To find the quotient of  3 ÷
1
4
, count the number of one-fourth parts.

There are 12 one-fourth parts.

So, 3 ÷
1
4
= 12
