Answer:
15
Step-by-step explanation:
Let n represent the number of twelvths in 5/4.
Expressed symbolically, this is n/12 = 5/4.
The LCD is 12. Multiply numerator and denominator of 5/4 by 3, obtaining:
n/12 = 15/12. Then n = 15.
There are 15 twelves in 5/4.
Answer:
1) 25/54 = 46%
2) 10/27 = 37%
3) 17/27 = 63%
4) 20/27 = 74%
5) 17/27 = 63%
6) 10/17 = 59%
Step-by-step explanation:
1) (50 male)/108 total) = 25/54
2) (40 thumbs down)/(108) = 10/27
3) (68 thumbs down or male) / (108) = 17/27
4) (80 thumbs down or female)/(108) = 20/27
5) (68 thumbs up)/(108) = 17/27
6) (40 thumb up female)/(68) = 10/17

Answer:
Step-by-step explanation:
Each of the 2-gallon mixes is made of 8 "parts" of paint, so each "part" is 2/8 gallons = 1/4 gallon = 1 quart. We can let <em>b</em> and <em>y</em> represent the costs of 1 quart of blue and yellow paint, respectively.
Then the cost for <u>2 gallons</u> is ...
3b + 5y = 58 . . . lime green
6b +2y = 64 . . . ocean blue
__
Subtracting the second equation from twice the first gives ...
2(3b +5y) -(6b +2y) = 2(58) -(64)
8y = 52
y = 6.5
From the first equation, ...
3b = 58 -5y = 58 -5·6.5 = 25.5
b = 25.5/3 = 8.5
The cost of 1 quart of blue paint is $8.50; the cost of 1 quart of yellow paint is $6.50.
