Part 1 = 2/9
Part 2 =5/9
Part 3 =7/9
Explanation
To convert the a repeating decimals this are the steps;
Part 1
Let x = 0.222222... (i)
10x = 2.222222... (ii)
Subtract equation (i) from equation(ii)
10x = 2.222222....
-x = 0.222222....
9x = 2.00000..
∴ 9x = 2
Divide by 9 both sides;
x = 2/9
Part 2
Let x = 0.5555...
10x = 5.5555...
subtract equation (i) from equation (ii).
10x = 5.5555..
- x = 0.5555..
9x = 5.0000..
∴ 9x = 5
x = 5/9
Part 3
Let x = 0.7777....
10x = 7.7777...
Subtracting equation (i) from equation (ii)
10x = 7.7777...
-x = 0.7777...
9x = 7.000..
∴ 9x = 7
x = 7/9
Pattern noted
When converting the repeating decimals to fraction only one number was repeating. This made the three decimals have the same fraction.
1. $1.27
2. $1.31
3. $2.00
4. $2.18
Answer:
Option 4: $2.18
Step-by-step explanation:
Lets first analyse our given information. We know that:
- Original Cost Per Jug: $0.80
- Mark Up cost: 150%
- Sales Tax: 9%
Now the Mark Up cost essentially means that the original price of any item has gone up (i.e. increased). So first let us find the Mark Up final cost of a $0.80 jug when price has increased by 150%, as follow:
Thus the jug after the mark up now costs $2.
Now lets compute the sales tax on the final jug cost, thus the 9% Tax on $2 as follow:
So finally the total cost of a jug of iced tea from A-1 Deli is $2.18 dollars (i.e. Option 4).

Hi Hello Hi Hello
How many pounds of blueberries did Kendra eat?
Answer:
Kendra ate 1/4 pounds of blueberries.
Step-by-step explanation:
The amount of blueberries Sean had = 1/3 pound
The amount of blueberries Kendra ate = 3/4 of Total available
= 3/4 of (1/3 pounds)
Now, we need to find out the 3/4 amount of 1/3 pound.
3/4 of 1/3 pound =
⇒ 3/4 of the amount 1/3 pound = 1/4 pound
Hence Kendra ate 1/4 pounds of blueberries.
