22 Mean Fractions want to take over control school blackboard. Finish them off as long as you can!!!

------------- HOW TO PLAY--------------

Every few seconds a new mean fraction appears on the blackboard.

To finsh it off you have to:

1. convert it to a natural number – the result of a division of the numerator by the denominator has to be a natural number,

OR

2. convert the sum of this fraction and any other fraction existing on the blackboard to a natural number

You can convert a fraction by multiplying it or dividing it by 2 or 3 as many times as can. Remember – the numerator and the denominator can never exceed 100.

You have three gaming modes:

PRACTISE

- the maximal initial denominator = 5

- in the new fraction - the numerator is always less than the denominator

- you can pause the game

STANDARD

- the maximal initial denominator = 10

- in the new fraction - the numerator is always less than the denominator

- less time for decision

HARD

- the maximal initial denominator = 15

- in the new fraction - the numerator can be greater than the denominator

- less time for decision

For each 100 points you get a BOMB. If you touch it – it falls down to the bottom of the blackboard and it's explosion destroys a few meanies. ;)
