Which of the following numbers is closest to 1: 1011, 100111, 1.101, 10001111, 1.011?
A number or a short expression. Fractions can be typed as 3/2, and spacing doesn't matter.
Solution
When we convert each of the possible answers to a decimal, we obtain 1.1, 1.11, 1.101, 1.111, and 1.011. Since the last of these is the only one greater than 1 and less than 1.1, it is closest to 1.
