Answer:
Twenty-one is 25% of 84 .
Step-by-step explanation:
Formula
\(Percentage = \frac{Part\ value\times 100}{Total\ value}\)
As given
Part value = 21
Percentage = 25%
Put all the values in the formula
\(25= \frac{21\times 100}{Total\ value}\)
\(25= \frac{2100}{Total\ value}\)
\(Total\ value = \frac{2100}{25}\)
Total value = 84
Therefore Twenty-one is 25% of 84 .
