Answer:
x/3 -3= 18 (add three to both sides)
x/3= 21
x/3(*3) =21(*3) (multiply by 3 on each side to cancel out the division)
x= 63
63/3-3=18
21-3=18
18= 18 (checking answers)
Step-by-step explanation:
15:24 is divisible by 3, simplifying it down to 3:8. 19:24, 7:8, and 6:8 are all obviously larger than this ratio, and 1:2 can be equalized to 4:8, which is also bigger than 3:8, so none of the answer choices are less than 15:24.
Answer:
315 people
Step-by-step explanation:
Using the given ratio, we can figure out the number of children on the train by doing cross multiplication.
Let x = # of children on train.
7/2 = 245/x
7x = 490
x = 70 children
The total number of people = 70 + 245 = 315 people total
