The discount percentage is 20%.
Given that the competitor is selling an item for $ 150.00, while the price for that item in the store is $ 120.00, the following calculation must be performed to determine the discount percentage:
- 150 = 100
- 120 = X
- 120 x 100/150 = X
- 80 = X
- 100 - 80 = X
- 20 = X
Therefore, the discount percentage is 20%.

4/100 Simplify to 1/25 4%
56/100 Simplify to 14/25 0.56
95/100 Simplify to 19/20 95%
Step-by-step explanation:
So, 7/5 is 1 and 2/5. 2/5 = 0.4 or 40% and 1 = 1 or 100%
4 is in the Hundredths column so it's 4 out of one hundred so 4/100 which is 4% , simplify the fraction by dividing by 4 to get 1/25
56% = 0.56 = 56 / 100 simplify to 14/25 by dividing by 4
0.95 = 95/100 simplify to 19/20 by dividing by 5 = 95%
