Answer: 22 to 55 to 44
Step-by-step explanation: Start with the factors you know. It can't be two because 2 doesn't go into 275 evenly. It can't be three because all of them evenly don't go into three. It can't be four because 110 and 275 don't go into it evenly. But five works. 110/ 5 is 22, 275/ 5 is 55, and 220/ 5 is 44.

Answer:
31 children and 290 adults
Step-by-step explanation:
Let a = number of adults and c = number of children.
a + c = 321
2a + 1.75c = 634.25
Multiply both sides of the the first equation by -2 and add it to the second equation.
-2a - 2c = -642
(+) 2a + 1.75c = 634.25
--------------------------------------
-0.25c = -7.75
Divide both sides by -0.25
c = 31
Use the first equation to find a.
a + c = 321
Substitute 31 for c.
a + 31 = 321
Subtract 31 from both sides.
a = 290
Answer: 31 children and 290 adults
Answer:
4 : 12 : 15
Step-by-step explanation:
S : J = 1 : 3
J : P= 4 : 5
Using John's ratio to find a common ratio for all
S : J
(1 : 3)4 = 4 : 12
J : P
(4 : 5)3 = 12 : 15
Therefore our ratio is
S : J : P
4 : 12 : 15
