Answer:

Step-by-step explanation:
You first calculate the product which is
+
to 
Then write all numerators above the least common denominator (
)
Now you have your answer.
Find the cost for one ticket for the science center.
36.75 ÷ 3 = 12.25
Multiply the product with 12 to get the cost of 12 tickets.
12.25 × 12 = 147
Find the cost of 1 zoo ticket.
51 ÷ 4 = 12.75
Find the cost of 12 tickets by multiplying the product and 12
12.75 × 12 = $153
12 Science Center Tickets cost $147
12 zoo tickets cost $153
The Zoo costs more than the Science Center.
To find out how much more the Zoo costed, subtract 147 from 153.
153 - 147 = 6
The zoo only costs $6 more for 12 students.
So, you're answers are Zoo and $6
Dividing the line segment AB into ratio 1:3 or 3:1 means dividing the line segment into four equal lengths, as shown in the diagram below.
Point P is the point that divides the line into 1 part and 3 parts, from A.
Point Q is the point that divides the line into 1 part and 3 parts, from B
Hence, P and Q are points on different position
