$\frac{21}{33.5} \cdot 100 = 62.69 %$ $21/(33.5)*100 = 62.69%$ (to 2 decimal places)

$62.69$ $62.69$ (2 d.p. )

Let $\frac{x}{100}$ $x/100$

represent the unknown percentage.
Then:

$\frac{x}{100} \cdot 33.5 = 21$ $x/100 * 33.5 = 21$

Multiply both sides by 100:

$x \cdot 33.5 = 2100$ $x * 33.5 = 2100$

Divide both sides by 33.5:

$x = 62.69$ $x = 62.69$ (2 d.p.)

$\frac{62.69}{100}$ $62.69/100$ or $62.69 %$ $62.69 %$
