Step-by-step explanation:
20% black dresses or suits
.35 = 35% wearing brown
1/4 = 25% wearing navy
100% -20% - 35% - 25% = 20% left
Answer:
4:8
Step-by-step explanation:
The 1 from the 1:2 is being multiplied by 4 for the 4:_, so the 2 from the 1:2 must also be multiplied by 4. 4 x 2 = 8
Using the information from the question, one can construct two equations:

... (1)

... (2)
by substituting (1) into (2) to find x


\frac{5}{4z} = \frac{1}{4}



⇒ z = 5
By substituting value of z into (1)
⇒ 4 (5) = x
⇒ x = 20
Thus the two numbers are 5 & 20
