So say 2.9999999999...... is 'x'
then 10x is 29.999999999999....
Now, I think we will all agree 10x - x = 9x Soooooooo Let's substitute
10x - x = 9x
29.9999999...... - 2.99999999.... = 27 = 9x Solve for 'x' by dividing both sides by '9'
3 = x But our original assumption was x = 2.999999999.....
Therefore 2.9999999..... = 3 Haha!
