Express 15g as a decimal fraction

Answer 1

just want to try
15*1kg/1000
15/1000=0.015

Answer 2

Correct, but you can simplify it:

1 kg = 1000 g

1 g = 1 / 1000 kg

15 g = 15 ∙ 1 / 1000 kg = 15 / 1000 kg = 5 ∙ 3 / 5 ∙ 200 kg = 3 / 200 kg

15 g = 3 / 200 kg

Answer 3

you forgot the units

15 g = 15/1000 kg
= .015 kg
