Standart of competation is understanding the number and perform arithmetic operation in proble solving.

Basic Competence is know fraction and perform operations fraction. The aid of learning program is getting the dessimal fraction.

Among other example of decimal fraction is 3,5 ; 0,33 ; 1,2 ; and 0,003. For example :

1.      0,33 mean 33/100

2.      1,2 mean 12/10

3.      0,03 mean 3/100

Know, we will expressed dessimal fraction , if we have number 0,45, its mean 45/100 and can be simplied 9/20 ( numerator and dominator divided by 5 ), and we will expressed fraction simplied to dessimal fraction. If we have a number 4/5 its mean 4 divide 5, so 4 : 5 is 0.8.

In conclution , Common fractions or mixed fractions can be expressed in the form decimal fractions. decimal fractions can be expressed in the form of ordinaryfractions or mixed fractions.
