Joseph is 2 m 30 cm tall. How tall is Joseph in millimeters?
A. 23,000 millimeters
B. 2,300 millimeters
C. 230 Millimeters
D. 23 Millimeters
To convert centimeters to millimeters, you need to multiply the value by 10. Therefore, to convert 30 centimeters to millimeters, you would multiply it by 10, which equals 300 millimeters.
Now, to convert meters to millimeters, you multiply the value by 1,000. Therefore, to convert 2 meters to millimeters, you would multiply it by 1,000, which equals 2,000 millimeters.
Adding the converted values, Joseph's height in millimeters would be 2,000 + 300 = 2,300 millimeters.
Therefore, the correct answer is: B. 2,300 millimeters.
Joseph is 2 m 30 cm tall. To convert this height to millimeters, we need to convert meters and centimeters to millimeters and then add them up.
1 meter = 1000 millimeters
So, 2 meters = 2 x 1000 = 2000 millimeters
1 centimeter = 10 millimeters
So, 30 centimeters = 30 x 10 = 300 millimeters
Adding the millimeters from meters and centimeters, we get:
2000 millimeters + 300 millimeters = 2300 millimeters
Therefore, Joseph is 2300 millimeters tall.
B. 2,300 millimeters
The answer is A. 23,000 millimeters.
To convert meters and centimeters to millimeters, we just need to remember that 1 meter is equal to 1000 millimeters, and 1 centimeter is equal to 10 millimeters.
Therefore, Joseph's height in millimeters would be:
2 meters = 2 x 1000 = 2000 millimeters
30 centimeters = 30 x 10 = 300 millimeters
Total height in millimeters = 2000 + 300 = 2300
So Joseph is 23,000 mm tall.
