If I had to convert 15 oz. to kg and it was given that 1 oz = 28.35 g and that 1 g = 1000 kg, how would I show my work to get the answer?

  • math - ,

    15 oz * 28.35g/oz * 1kg/1000g = 0.425 kg

    note how the units cancel, just like common factors

    okay, thanks! can you also look at this one for me? I'm having trouble getting the right answer.
    4 kg to oz.
    1 oz = 28.35 g
    1g = 1000 kg
    4kg x 28.35 g/ 1oz = 113.4 g
    113. 4 g x 1 oz / 1000kg = 0.11 oz
    The answer is supposed to be 141 oz

  • math - ,

    gotta make the units cancel.
    kg*g/oz makes no sense

    kg * g/kg * oz/g = oz

    4kg * 1000g/1kg * 1oz/28.35g = 141 oz

  • math - ,

    what you are doing is multiplying by 1, which does not alter the value

    1oz = 28.35g, so

    1oz/28.35g = 1
    28.35g/1oz = 1

    which one you use determines which units cancel
