‎7.99(Repeating) = 8
Wanna know how? Smile

10x = 79.99(Repeating)
x = 7.99(Repeating)

10x - x
79.99(Repeating) - 7.99(Repeating)

9x = 72

72/9 = 8
x = 8

So is your brain hurting now? Very Happy

Now look at this...

9 x 7.99(Repeating) = 71.99(Repeating)
71.99(Repeating) / 9 = 7.99(Repeating)

x =/= 8

Well now, I don't really know how to explain this Smile
