How do you write 4.28 meters as a mixed number in it's simplest form?

Question

Kim built a model railroad using 4.28 meters of track. How can he write his number as a mixed number in simplest form

Answer 1

The number 4.28 can be expressed as 4 28/100.

Then we need to reduce the fraction by dividing top and bottom by 4 to get 7/25

So the final answer is:

4 7/25

 

Answer 2

1)  4.28 meters can be expressed as the sum of 4 meters and 0.28 meters.

        

         4+0.28 meters  

2) As 1 meter is equal to 1oo centimeters, 0.28 meters will be equal to 28 centimeters. This can be  

    expressed as 28/100. therefore, 4.28 meters may be written as follows:

    

        4 + (28/100) meters 

 

3) Representing the same as a fraction, it will reduce to  4 (28/100) meters

 

4)  Simplifying  the fraction within the brackets ( 28/100) further, it will reduce to  ( 7/25).

 

5)  Thus 4.28 meters can be represented as a mixed number 4 7/25  or  4 (7/25) more clearly.

 

Hope this helps....
