<h3>What is the ratio?</h3>
It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign : between the numbers.
We have:
Pink to black = 8:7
Black to yellow = 1:5
Let's suppose the pink is 8x
Black = 7x
Yellow = 7(5x) = 35x
Percent of black = 7x(100)/(8x+7x+35x)
Percent of black = 14%
Thus, the percent of black is 14% if the bag contains only pink, black and yellow marbles the ratio is 8:7 the ratio of black to yellow is 1:5
