Answer:
Angela, a proportion is two equal ratios, kinda like 3/4 = 6/8.
If we call the number of cars c, then our proportion is 3/10 = c/100.
Cross multiplying, we get 10c = 300.
Dividing both sides by 10, c = 30.
We can solve this by setting up a proportion:
12 seeing the play/ 72 students = 210 seeing the play/ x students
We can cross multiply to solve for x:
(12)x=(72)(210)
12x=15,120
x=1,260 students who attend the school
Hey, there!
The parentheses would make it multiplication
The word sum means add
A number was unknown, so we will label it as "x"
So, let's see what we're working with here!
If you chose "Option A" the question would be "five multiplied by a number and the sum of 3" (that doesn't give you the right answer"
For B. same thing with option A
For "Option C" its not asking you "a number with sum of three times five"
So, this leaves "Option D." as your answer because 3 is getting multiplied by the sum of some number and five
Good luck on your assignment and enjoy your day!
