Each of the following objects have been measured with inappropriate units. Convert them to more suitable units. (Please check my work and see if the units are correct for the situation?)
a) The thickness of a dime is 0.00122m
0.00122m*100cm/1m = 0.122cm
b) The height of a basketball player is 2100 mm
2100mm*1m/1000mm = 2.1m
c) The driving distance from Pincher Creek to Taber is 14,900,000cm
14,900,000cm*1m/100cm*1km/1000m = 149km
a) ok., but mm would be better. Avoid units smaller than 1 if possible.
b) Right.
c) Right.
a) The thickness of a dime is 0.00122m. To convert this measurement to more suitable units, you correctly multiplied by 100 to convert meters to centimeters. So, the converted measurement would be 0.122cm.
b) The height of a basketball player is 2100 mm. To convert this measurement to more suitable units, you correctly multiplied by 1m/1000mm to convert millimeters to meters. So, the converted measurement would be 2.1m.
c) The driving distance from Pincher Creek to Taber is 14,900,000cm. To convert this measurement to more suitable units, you correctly multiplied first by 1m/100cm to convert centimeters to meters, and then by 1km/1000m to convert meters to kilometers. So, the converted measurement would be 149km.
Based on the conversions you provided, it appears that your calculations are correct, and the units you arrived at are appropriate for each situation.
