Answer: the fraction that is closer to one and a half is 2/4.
Explanation:
To determine which fraction is closer to one and a half, we can compare the given fractions to the decimal representation of 1.5.
1/2 = 0.5
4/2 = 2
6/2 = 3
2/4 = 0.5
Among the given fractions, 1/2 and 2/4 have decimal representations that are equal to 0.5, which is less than 1.5. Therefore, neither 1/2 nor 2/4 is closer to one and a half.
On the other hand, 4/2 has a decimal representation of 2, which is greater than 1.5. Similarly, 6/2 has a decimal representation of 3, which is even further from 1.5.
