Answer:
100%
Step-by-step explanation:
Start with x.
x = x/1
Increase the numerator by 60% to 1.6x.
Decrease the numerator by 20% to 0.8.
The new fraction is
1.6x/0.8
Do the division.
1.6x/0.8 = 2x
The fraction increased from x to 2x. It became double of what it was. From x to 2x, the increase is x. Since x was the original number x is 100%.
The increase is 100%.
Item A and B are in decimal format, convert Item C to decimal by changing the fraction to a decimal by dividing 11 by 16:
11 / 16 = 0.6875
This makes Item C 3.6875
Now you have the 3 items as decimal format now put them in order from smallest to largest:
3.65, 3.6875, 4.1
Item A, Item C, Item B
1 True because 19^3 = 6859
2. False
3. True because 8000 ^1/3 can be written as 100^1/3 * 8^1/3
4 False
5 True because they are both = 15
