Help last one thanks guys for helping but explain in a way i would understand

Serggg [28]

OK, like I explained in the last one KCF, (Keep Change Flip) so our problem is:
8/7÷5/8 So lets Keep 8/7 and change the divide sign to multiplication sign. and then for Flip you flip 5/8 to 8/5. So now our real problem is: 8/7*8/5= (8*8=64) and (7*5=35). So we have 64/35, now you just need to change this improper fraction to a proper one... message me if you have any trouble :)

Sum of series to n terms 0.4+0.44+0.444+....

svetoff [14.1K]

$0.4+0.44+0.444+\cdots=\dfrac4{10}+\dfrac{44}{100}+\dfrac{444}{1000}+\cdots=\displaystyle\sum_{k=1}^\infty\frac{\frac49(10^k-1)}{10^k}=\frac49\sum_{k=1}^\infty\left(1-\frac1{10^k}\right)$

The $n$ th partial sum is given by

$S_n=\displaystyle\frac49\sum_{k=1}^n\left(1-\frac1{10^k}\right)$
$S_n\displaystyle=\frac49\bigg(\left(1-\frac1{10}\right)+\left(1-\frac1{100}\right)+\cdots+\left(1-\frac1{10^{n-1}}\right)+\left(1-\frac1{10^n}\right)\bigg)$
$S_n=\dfrac49\left(n-\dfrac{10^n-1}{9\times10^n}\right)=\dfrac4{81}(9n-1+10^{-n})$

from which it follows that the infinite sum does not converge.
