Answer:
1, 2, and 3
Explanation:
5% = 0.05 = 1/20
The first expression is equal, as 5% is equal to 1/20.
The second expression is equal, as 5% in decimal form is 0.05.
The third expression is equal, as 5% is 5/100 in fraction form, which can be simplified to 1/20.
The fourth expression is NOT equal, as it is 20%, not 5%. 1/5 = 0.2.
The fifth expression is NOT equal becauase 0.5 is one half (1/2), which is not equal to 0.05.
