The 6 in 60 is how many times greater than the 6 in 6?
100 times greater
10 times greater
same value
10 times smaller
Explanation
On a place value chart (ones, tens, hundreds), the tens place is 10 times the ones place. The 6 in 6 is 6 ones. The 6 in 60 is 6 tens, which is 60. So 60 is 10 times bigger than 6.
The 5 in 50,000 is how many times greater than the 5 in 5,000?
100 times greater
same value
10 times greater
10 times smaller
Explanation
In a place value chart, the 5 in 5,000 is in the thousands place, and the 5 in 50,000 is in the ten-thousands place. Each step left is 10 times bigger, so ten-thousands is 10 times thousands.
The 3 in 300 is how many times bigger than the 3 in 30?
same value
10 times smaller
100 times greater
10 times greater
Explanation
Moving one place left on a place value chart multiplies by 10. The 3 in 30 is in the tens place (3 tens). The 3 in 300 is in the hundreds place (3 hundreds). Hundreds are 10 times tens, so it is 10 times greater.
Which statement is true?
The 8 in 800 is 10 times greater than the 8 in 80.
The 8 in 800 is 100 times greater than the 8 in 80.
The 8 in 800 has the same value as the 8 in 80.
The 8 in 800 is 10 times smaller than the 8 in 80.
Explanation
On a place value chart, 80 has the 8 in the tens place and 800 has the 8 in the hundreds place. Hundreds are 10 times tens, so the value is 10 times greater. The other choices describe 100×, same, or ÷10, which are not correct here.
