<span> let x = # of adult tickets
sold, thus the # of children tickets
= 70-x</span>
<span> 7.5x + 5(70-x) = 450</span>
<span> ^ 7.5x + 350 -5x = 450</span>
<span> ^ 2.5x = 450-350= 100</span>
<span> x = 40 adults
tickets thus
70—40 = 30 children tickets</span>
275 + 180 + 120 = 275 + 300 = 575
not 100% that this is right but this is my best guess. Hope this helps!!

Answer:
1/9, 2/8, 3/7, 4/6
Step-by-step explanation:
The fraction will be proper when the numerator is less than the denominator. That means numerators can be less than 10/2 = 5. The fractions that satisfy the requirement are ...
1/9, 2/8, 3/7, 4/6
Those with even numerators can be reduced. So the reduced fractions are ...
1/9, 3/7
