Initial number that is given in the question = 280
Final number that is given in the question = 289
Total amount of increase in the number = 289 - 280
= 9
Then
Percentage of increase in the given number = (9/280) * 100
= 90/28
= 45/14
= 3.21 percent
So the percentage increase in the number is 3.21%. <span>I hope
the procedure is clear enough for you to understand. This will help you to

Hello,
let's say x is a certain number
10*x+9+2x=633
12x=624
x=52
Proof:
529+104=633
Answer:
7. 1/3
8. 1/6
9. 13/24
10. 5/8
11. 17/24
12. 0
Step-by-step explanation:
First find the total number balls by summing the indiviudal number of balls:
Total = 5 + 8 + 7 + 4 = 24
Then, the find any probability divide the number of ways your selected situation can happen from the total:
![probability = \frac{number.of.possible.ways}{total.number.of.ways}](https://tex.z-dn.net/?f=probability%20%3D%20%5Cfrac%7Bnumber.of.possible.ways%7D%7Btotal.number.of.ways%7D)
A final step if you want is to reduce the fraction to its simplest value. For example,
![\frac{2}{4} =\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B4%7D%20%3D%5Cfrac%7B1%7D%7B2%7D)
7) 8/24 = 1/3
8) 4/24 = 1/6
9) (8+5)/24 = 13/24
10) (24 - 5 -4)/24 = 15/24 = 5/8
11) (24 - 7)/24 = 17/24
12) (0)/24 = 0
