The yeast cake contains milk, yeast, sugar, and flour in a ratio of 20: 4: 1: 15. What percentage of flour is in yeast?

Result

p =  37.5 %

Solution:

f=1520+4+1+15=38=0.375  p=100 f=100 0.375=752=37.5=37.5%f = \dfrac{ 15 }{ 20+4+1+15 } = \dfrac{ 3 }{ 8 } = 0.375 \ \\ \ \\ p = 100 \cdot \ f = 100 \cdot \ 0.375 = \dfrac{ 75 }{ 2 } = 37.5 = 37.5 \%
