Answer 2

$\huge{\mathtt{\color{magenta}{✤ ANSWER ✤ }}}$

$\dfrac{54m}{45m}$

You can cancel the units :-

$\dfrac{54}{45}$

$\dfrac{54}{45} = \dfrac{6}{5} = 1.2$

Finally, convert 1.2 into a percent:

1.2 = 120%

As you started with 100% , subtract that to find your percent increase.

120% − 100% = 20%

$\huge{\mathtt{\boxed{\color{lime}{20\:percent}}}}$
