# <menuchoice>Arithmetic</menuchoice> - in this exercise you have to solve a given fraction task. You have to enter numerator and denominator. This is the main exercise. The difficulty of this task can be influenced by the user. The user can decide if he wants to solve tasks with addition/subtraction and/or multiplication/division. Also he can set the number of fractions and the maximum size of the main denominator. # <menuchoice>Comparison</menuchoice> - in this exercise you have to compare the size of 2 given fractions. # <menuchoice>Conversion</menuchoice> - in this exercise you have to convert a given number into a fraction. # <menuchoice>Factorization</menuchoice> - in this exercise you have to factorize a given number into its prime factors. Factorization is important while finding the main denominator of 2 fractions. # <menuchoice>Percentage</menuchoice> - in this exercise you have to calculate easy parts of numbers given as percentages.‎

{| | [[Image:kbruch-learning.png|230px|thumb]] | The main goal in ''learning mode'' is to make the parts of the inner ring and the outer ring have the same size. The corresponding fractions can be expanded using spin boxes. The learner can get advice reading the hint box on the right. |- | [[Image:kbruch-common.png|230px|thumb]] | Here you can see the exercise ''Arithmetic.''
