Question

The mass of a standard hockey puck must be at least 156 grams. What is the minimum mass of 8 hockey pucks in kilograms?

Answer 1

you can solve this a few ways but i’ll give you the easiest.
156x8=1248

1gram=0.001 grams so you could basically take the last three numbers (248) and put them behind the decimal, with the 1 in front of the decimal.
now you have 1.248

hope it helps
