Base, Rate & Percentage

To identify which statement is correct, prove that any of the three formulas are true.

[tex]\Large \tt Base = \frac{Percentage}{Rate}[/tex]

[tex]\Large \tt Rate = \frac{Percentage}{Base}[/tex]

[tex]\Large \tt Percentage = Base \times Rate[/tex]

(Use the formula for Percentage for a much more easier solution)

20% of 50 is 20

[tex]\large \tt Percentage = Base \times Rate[/tex]

[tex]\large \tt 20 = 50 \times 20\%[/tex]

[tex]\large \tt 20 = 50 \times 0.2[/tex]

[tex]\large \tt \red{20 = 10}[/tex]

[tex]\Large \tt \red{FALSE}[/tex]

30% of 15 is 35

[tex]\large \tt Percentage = Base \times Rate[/tex]

[tex]\large \tt 35 = 15 \times 30\%[/tex]

[tex]\large \tt 35 = 15 \times 0.3[/tex]

[tex]\large \tt \red{35 = 4.5}[/tex]

[tex]\Large \tt \red{FALSE}[/tex]

┉┉┉┉┉┉┉┉┉┉┉┉┉┉┉┉┉┉

40% of 80 is 32

[tex]\large \tt Percentage = Base \times Rate[/tex]

[tex]\large \tt 32 = 80 \times 40\%[/tex]

[tex]\large \tt 32 = 80 \times 0.4[/tex]

[tex]\large \tt \color{lime}{32 = 32}[/tex]

[tex]\Large \tt \color{lime}{TRUE}[/tex]

┉┉┉┉┉┉┉┉┉┉┉┉┉┉┉┉┉┉

Answer:
