Answer:

A digit that makes this sentence true is 4.

Explanation:

Since the first digit in the number to the left is 3, you simply have to find a digit greater than 3. Here are the possibilities:

4

5

6

7

8

and

9

Out of any of these you can choose, I chose 4.

Answer:

3, or any greater digit

Explanation:

Suppose the digit is 'd'. Then the value on the right is ...

69.436 +100d

Subtracting the value on the left, we want the difference greater than 0.

69.436 +100d - 352.934 > 0

100d -293.498 > 0 . . . . simplify

100d > 293.498 . . . . . . . add 293.498

d > 2.93498 . . . . . . . . . . divide by 100

That is d is any single digit greater than 2.9. Those digits are ...

d ∈ {3, 4, 5, 6, 7, 8, 9}

Any digit 3 or greater makes the sentence true.
