Answer
Find out the 450 is 75 percent of what number .
To prove
Formula
\(Percentage = \frac{Part\ value\times100}{Total\ value}\)
As given
450 is 75 percent
thus
Percentage = 75%
Part value = 450
Put in the formula
\(75 = \frac{450\times100}{Total\ number}\)
\(Total\ number = \frac{45000}{75}\)
Total number = 600
Therefore 450 is 75 percent of 600.
