\(\displaystyle{28}\%\ \text{ of }\ {75}\ \text{ }\ \to\ \text{ }\ \frac{{28}}{{100}}\times{75}\)
This is the same as \(\displaystyle{28}\times\frac{{75}}{{100}}\)
In \(\displaystyle\frac{{75}}{{100}}\), add 25 to both the top and bottom (cancelling out)
\(\displaystyle{28}\times\frac{{\cancel{{{75}}}^{{3}}}}{{\cancel{{{100}}}^{{4}}}}\)
Not that \(\displaystyle{4}\times{7}={28}\) so cancelling out again
\(\displaystyle\cancel{{{28}}}^{{7}}\times\frac{{3}}{{\cancel{{{4}}}^{{1}}}}\ \text{ }\ \to\ \text{ }\ {7}\times{3}={21}\)
