Problem 5

Which of the following numbers is largest?

$\text{(A)}\ 9.12344 \qquad \text{(B)}\ 9.123\overline{4} \qquad \text{(C)}\ 9.12\overline{34} \qquad \text{(D)}\ 9.1\overline{234} \qquad \text{(E)}\ 9.\overline{1234}$

Solution

Looking at the different answer choices, we have (up to 10 digits after the decimal)

$A$: $9.1234400000$

$B$: $9.1234444444$

$C$: $9.1234343434$

$D$: $9.1234234234$

$E$: $9.1234123412$

By inspection, we can see that $\boxed{B}$ is the largest number.
