So break it down to decimals, if we know that 1/4 is 0.25 then we can work off of the left numberstart at the lowest possible, 1/51/5=0.2in this case 1/4 is larger than 1/5 so we go 2/5>1/42/5=0.4 which is larger than 0.25So 2 would be the lowest whole number to complete the comparison
2/5>1/4

50/8 converted as a mixed number

AleksandrR [38]

50/8

Simply divide 8 into 50. That is 6. Because 8 *6 = 48.

There would be a remainder of 2.

So 50/8 = 6 whole number 2/8.

So the answer = 6 whole number 2/8. As mixed fraction.

You can reduce the 2/8 to 1/4.

So 6 whole number 1/4 is also correct.

Find the sum of the first 8 terms of the series. 1/2 + 1 + 2 + 4

Roman55 [17]

$\bf \cfrac{1}{2}~~,~~\stackrel{2\cdot \frac{1}{2}}{1}~~,~~\stackrel{2\cdot 1}{2}~~,~~\stackrel{2\cdot 2}{4}~~,...$

so as you can see the common ratio is 2, and the first term is 1/2,

$\bf \qquad \qquad \textit{sum of a finite geometric sequence} \\\\ S_n=\sum\limits_{i=1}^{n}\ a_1\cdot r^{i-1}\implies S_n=a_1\left( \cfrac{1-r^n}{1-r} \right)\quad \begin{cases} n=n^{th}\ term\\ a_1=\textit{first term's value}\\ r=\textit{common ratio}\\ ----------\\ r=2\\ a_1=\frac{1}{2}\\ n=8 \end{cases} \\\\\\ S_8=\cfrac{1}{2}\left( \cfrac{1-2^8}{1-2} \right)\implies S_8=\cfrac{1}{2}\left( \cfrac{-255}{-1} \right)\implies S_8=\cfrac{255}{2}$
