$68.57 %$ $68.57%$ of $17.5$ $17.5$ is $12$ $12$

Let $x$ $x$ be the percent of 17.5 that is 12

We can write the expression as:

$\frac{x}{100} \times 17.5 = 12$ $x /100 \times 17.5 = 12$

transposition

$\frac{x}{100} \times 17.5 = 12$ $x /100 \times 17.5 = 12$

$x \times 17.5 = 12 \times 100$ $x \times 17.5 = 12\times 100$

$x = \frac{12 \times 100}{17.5}$ $x = (12\times 100)/ 17.5$

$x = 68.57$ $x = 68.57$ --------(approximately after truncating the value up to two decimal places)

$68.57 %$ $68.57%$ of $17.5$ $17.5$ is $12$ $12$

$= 68 \frac{4}{7} % or 68.6$ $=68 4/7% or 68.6$ to one decimal place.

To find what percent one quantity is of another, you can use the method:

$fraction×100%$ $"fraction" xx 100%$

It is easier to ask the question the other way round because that helps to identify the fraction. One number is a fraction of another.

What percent is $12 out of 17.5 ?$ $12 " out of " 17.5?$

$\frac{12}{17.5} \times 100 % \leftarrow (\times 100 % = \times 1)$ $12/17.5 color(blue)(xx 100%)" "larr (color(blue)(xx 100% = xx1))$

$=68.57142857....$

(You might recognise the recurring decimals as 'sevenths')

$=68 4/7% or 68.6$ to one decimal place.
