The ration is 170 adults:150 children, or 170/150We can factor out a 10 from both numbers, which leaves us with
17 adults/15 children.17 and 15 have no other factors, so that's the smallest ratio we can have.

A common denominator is when 2 fractions have the same denominator and a common multiple is when two multiples have at least 1 number alike
Example: Common Denominator
4/10 6/10
Example: Common Multiple
2: 2,4,6,8,10,12
4: 4,8,12
Answer: x = 15
Step-by-step explanation:
1) Set q(x) = 3 in the equation.
3 = (4/5)x - 9
2) Add 9 to both sides.
12 = (4/5)x
3) Multiply by 5/4 on both sides.
15 = x
x = 15
Answer:
Question 2: A. Overlapping lines.
The equations are identical; and if we would treble the first equation, we get the second equation.
Question 3: B. Multiply the second equation by -3 to get
