X=the percent in%
therefore, we suggest this equation:
28(x/100)=21
x=(21*100)/28=75

75%

To check:
75% of 28=(75/100)28=(75*28)/100=21

80% of 45=(80/100)45=(80*45)/100=36

36

Step-by-step explanation:

Podemos probar esto encontrando el máximo común divisor entre 21 y 45

21: 1,3,7,21

45: 1,3,5,9.15,45

Encontramos que 3 es el máximo factor común. Entonces dividimos ambos números por 3. Para obtener 7:15.
