Jennifer has built a shelf which can safely support 16.40 pounds. If there are 2.20462 pounds in a kilogram, how many kilograms can Jennifer’s shelf support?
Accepted Solution
A:
Multiply the original 16.40 lb by the conversion factor (1 kg) / (2.20462 lb):
16.40 ------------- kg = 7.44 kg. Round off to 2 decimal places because 16.40 lb is 2.20462 accurate only to 2 dec. places.
