Question

select all the true sentences. 616,801 > 618,810; 188,160 > 686,108; 682,611 > 682,611; 688,117 > 686,118

Explanation:

Step1: Compare 616,801 and 618,810

To compare two numbers, we start from the leftmost digit. The hundred - thousands digit is 6 for both. The ten - thousands digit is 1 for both. The thousands digit: 6 < 8. So 616,801 < 618,810, so the statement \(616,801>618,810\) is false.

Step2: Compare 188,160 and 686,108

The hundred - thousands digit: 1 < 6. So 188,160 < 686,108, so the statement \(188,160 > 686,108\) is false.

Step3: Compare 682,611 and 682,611

By the definition of equality, a number is not greater than itself. So \(682,611>682,611\) is false.

Step4: Compare 688,117 and 686,118

The hundred - thousands and ten - thousands digits are the same (6 and 8). The thousands digit: 8>6. So when the thousands digit of the first number is greater than the thousands digit of the second number, we can conclude that 688,117>686,118. So the statement \(688,117 > 686,118\) is true.

Answer:

The only true sentence is \(688,117>686,118\) (the last option).
