Question

when a cake is cut in 3 equal parts then every part will be equal to 33.33% so the sum of three parts will be 33.33%+33.33%+33.33%=99.99% so where is that 0.01%.​

Answer 1

3 ×1/3 =3×0.333...=0.999...

Let x=0.999...

10x=9.999...

10x-x=9.999...-0.999...

9x=9

x=1

That is so because 1/3 is *not exactly equal to* 0.333333.

0.333333 is an approximation of 1/3 which is correct to 6 decimal places.
