Ava's mother is 36, A+3A+2(3A)=120. 12+36+72=120. A=12. The smallest number is 12.5, X+(X+4)+2x=54. 12.5+16.5+25=54 :)
<span>To answer this question you need to find the highest number below 30 which can be divided by 8 (for 7/8) and 3 (for 2/3). This number would be 24. So 21 own football boots, 16 own a football and there are 24 children in the class.
Hope this helps!!!</span>

The other factor is 
Answer:
2 touchdowns, 3 field goals
Step-by-step explanation:
The number of touchdowns cannot be more than 3, so it is relatively easy to find the solution by trial and error.
23 is not divisible by 3, so 0 touchdowns is not a solution
23 -7 = 16 is not divisible by 3, so 1 touchdown is not a solution
23 -14 = 9 is divisible by 3, so 2 touchdowns and 3 field goals is a solution
21 -21 = 2 is not divisible by 3, so there is only one solution.
