A, D, and E are true statements.
The true statements are:
A. 11 meters = 1,100 centimeters
B. 7 centimeters = 700 millimeters
C. 5 meters = 500 centimeters
D. 12 centimeters = 120 millimeters
E. 9 kilometers = 900 meters
To determine which statements are true, we need to convert the given units of measurement and verify if the values are equal.
A. 11 meters = 1,100 centimeters
To convert meters to centimeters, we multiply the number by 100. So, 11 meters = 11 * 100 = 1,100 centimeters.
B. 7 centimeters = 700 millimeters
To convert centimeters to millimeters, we multiply the number by 10. So, 7 centimeters = 7 * 10 = 70 millimeters. Therefore, this statement is incorrect.
C. 5 meters = 500 centimeters
Using the same conversion factor as in statement A, we find that 5 meters = 5 * 100 = 500 centimeters.
D. 12 centimeters = 120 millimeters
As we found in statement B, 7 centimeters is equal to 70 millimeters. So, 12 centimeters = 120 millimeters. This statement is true.
E. 9 kilometers = 900 meters
To convert kilometers to meters, we multiply the number by 1,000. So, 9 kilometers = 9 * 1,000 = 9,000 meters. Therefore, this statement is incorrect.
Based on our conversions, the true statements are:
A. 11 meters = 1,100 centimeters
C. 5 meters = 500 centimeters
D. 12 centimeters = 120 millimeters
