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!

 

\(a=\dfrac{4}{100}\cdot b\ |\ \cdot \frac{100}{4}\\ b=25a\\ b=\dfrac{25}{100}\cdot c\\ \ b\ equate\)

\(\dfrac{25}{100}\cdot c=25a\ |\ \cdot \frac{100}{25}\\\)

\(c=\dfrac{25\cdot 100}{25}\cdot a\\ \color{blue}c=100\cdot a\)

 

\(c\ is 100\cdot 100\%=\color{blue}10\ 000\%\ of\ a.\)
