I tried this:

Explanation:

Let us use fractions and compare numbers and percentages:
$\frac{55}{34} = \frac{100 %}{x %}$ $55/34=(100%)/(x%)$
rearrange:
$x % = \frac{34}{55} \cdot 100 % = 61.8 %$ $x%=34/55*100%=61.8%$

Answer 2 · 2018-02-07T20:31:40

$\frac{680}{11} %$ $680/11%$

Explanation:

I think the easiest way to do this is by using proportions.

In this case, $55$ $55$ is the original and $34$ $34$ is part of $55$ $55$ , so $55$ $55$ would be $100 %$ $100%$ and $34$ $34$ would be $x %$ $x%$ .

$(\frac{55}{100})$ $(55/100)$ = $(\frac{34}{x})$ $(34/x)$

Using cross multiplication you get:

$55 x = 3400$ $55x = 3400$

$11 x = 680$ $11x = 680$

$x = \frac{680}{11}$ $x = 680/11$

So $34$ $34$ is $\frac{680}{11} %$ $680/11%$ of $55$ $55$ .
