The correct statement or mathematical
expression in the choices given is:
900 is 100 times as much as 9.
Because if you multiply 9 x 100 (100
times as much as 9) = 900.
Hence,
1. 1/10 of 100 = 10
2. 1000 times as much as 90 or 1000 x 90 = 90, 000
3. 9 is 1/10 of 900 or 900 is divided by 10: 900 / 10 = 90
