Circle the number that is 10 times greater than nine hundred and seven. 9700, 907, 9007, 970, or 9070.

So the question is asking us to circle the number 10 times greater than nine hundred and seven. We can use a place value chart to make sure that we write nine hundred and seven the correct way. This number has nine hundreds, no tens, and seven ones. The question asks us to find the number 10 times greater than 907. So we need to multiply 907 by 10.

We could simply say that when we multiply a number by 10, we add a zero on the end. So 907 multiplied by 10 is equal to 9070. If we add 9070 to the place value chart, we can see that each digit moves one place to the left. The seven digit has moved from the ones to the tens. It’s 10 times bigger. The zero digit in 907 has moved from the tens into the hundreds column. This means it has also got 10 times bigger. And the nine in 900 has become 9000. This has also become 10 times bigger. 907 multiplied by 10 equals 9070.

The question asks us to circle this number. To find the number that is 10 times greater than 907, first we wrote 907 using digits in our place value chart. We found the number 10 times greater than 907 by moving each of the digits one place to the left in the place value chart. This gave us an answer of 9070. And the question asked us to circle this number.
