Janice thinks that 20 hundredths is equivalent to 2 thousandths because 20 hundreds is equal to 2 thousands. use words and a place value chart to correct janice's error.

Explanation:

On the left hand side of the place value chart, 20 hundreds is equal to 2 thousands because thousands is larger than hundreds. 2 thousands is 2(1000)=2000. 20 hundreds is 20(100)=2000. They are the same number.

However, on the right hand side of the place value chart, hundredths is larger than thousandths. To say that 20 hundredths is the same as 2 thousandths is incorrect, because you're saying more of a larger quantity is the same as less of a smaller quantity.

Hundredths are two places after the decimal, and have a value of 0.01. 20 hundredths is 20(0.01) = 0.2.

Thousandths are three places after the decimal and have a value of 0.001. 2 thousandths is 2(0.001) = 0.002.

We can write 0.2 as 0.200; this way we can see that 0.200 is larger than 0.002. They are not equal.
