This activity aims to teach fractions and make the kid works on both numerator and denominator.
# User needs to create the denominator first by clicking on a button which adds a row
# After representing the denominator, user needs to select a part of them to represent the numerator.
Example:
If the displayed fraction is 1/2 and 1 row is already displayed, then:
# User needs to click on the button, to add an extra row, therefore 2 rows will be there which represents the denominator.
# Then user can select 1 row, (may be we can change the color of the row which will be selected), therefore this selected row is the numerator.
we can have another button for adding columns, it will be used in case we have a fraction greater than 1.
adding a column means that we multiply the numerator by 2.
