What is the relationship between the 6s in the number 660,472
wlad13 [49]

Answer:

The first 6 is 10 times greater than the second one


Explanation:

The given number is 660,472

This number can be rewritten as:

660,472 = 600,000 + 60,000 + 400 + 70 + 2


Now, comparing this to the place-value chart shown in the attached image, we would find that:

The first 6 represents the hundred thousands of the number

The second 6 represents the ten thousands of the number

The 0 represents the thousands of the number

The 4 represents the hundreds of the number

The 7 represents the tens of the number

The 2 represents the ones of the number


Now, we are comparing the values of the 6s:

The first 6 represents the hundred thousands of the number

The second 6 represents the ten thousands of the number

This means that:

The first 6 is 10 times greater than the second one


Hope this helps :)
