A good way to set up percentage problems is by using "Part = Percent × Whole".
In this case, our part is 140, our percent is 80 (because that 20% wa s took of from the original 100%), and our whole is unknown. If we fill in the equation we get this:
140=80×x.
if we solve the equation by dividing both sides by 80, we get $1.75=x. Because we replaced 80% with 80,we have to divide by 100 since we multiplied by 100 in the beginning. So, we get that $175 was the original price.

Hello There!
These statements are not equal. If you solve them, you will not get the same value.
Hope This Helps You!
Good Luck :)
Answer:
A is bigger
Step-by-step explanation:
lets say the certain number is 10 and if its 20% of Number A that would mean that number A is 50 and that would also mean that number B is 25 so since 50 is bigger then 25 that would mean number A is bigger
Given:
Total number of cubes = 40
Red cubes = 18
Blue cubes = 13
Yellow cubes = 9
Aysha adds some more red cubes into the bag.
The probability now that she will take a red cube is 0.5.
To find:
The probability that she will take a yellow cube.
Solution:
Let Aysha adds x red cubes into the bag. Then,
Number of total cubes = 40+x
Number of red cubes = 18+x
Probability of getting a red cube is:
The probability now that she will take a red cube is 0.5. So,
Divide both sides by 0.5.
It means Aysha adds 4 more red cubes into the bag.
Now, the total number of cubes int he bag is:
Probability of getting a yellow cube is:
Therefore, the required probability is .
