Pls help, Thank you.
If a is 4 percent of b and b is 25 percent of c, what percent of a is c??
c = 100
b = 25% of c = 25
a = 4% of b = 1
c = 10,000% of a

Hello weredumbmaster!
\(a=\dfrac{4}{100}\cdot b\ |\ \cdot \frac{100}{4}\\ b=25a\\ b=\dfrac{25}{100}\cdot c\\ \ b\ equate\)
\(\dfrac{25}{100}\cdot c=25a\ |\ \cdot \frac{100}{25}\\\)
\(c=\dfrac{25\cdot 100}{25}\cdot a\\ \color{blue}c=100\cdot a\)
\(c\ is 100\cdot 100\%=\color{blue}10\ 000\%\ of\ a.\)
