Question

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.

Answer 1

20 hundredths = 20/100 = 0,2
2 thousandths = 2/1000 = 0,002

20 hundreds = 20 * 100 = 2000
2 thousands = 2 * 1000 = 2000

20 hundreds is equal to 2 thousands, however 20 hundreths is not equal to 2 thousandths. 2 in the 0,2 is 100 times greater than 2 in 0,002.
