Answer:
10.9
Step-by-step explanation:
Formula = Number x 100
Percent = 6 x 100
55 = 10.91
Following shows the steps on how to derive this formula
Step 1: If 55% of a number is 6, then what is 100% of that number? Setup the equation.
6
55% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
55Y = 6 x 100
55Y = 600
Y = 600
100 = 10.91

Answer:
Brody purchased 16 songs.
Step-by-step explanation:
Ratio of the number of songs purchased by Brody(B) and Jayliah(J) = 2 : 3
------(1)
Similarly ratio of the songs purchased by Jayliah(J) and Sadie(S) = 4 : 5
-------(2)
If Sadie bought the songs (S) = 30

B = 
B = 16
Therefore, number of songs purchased by Brody = 16.
