Question

Multiple Choice Question Mara has a digital scale. He placed one playing card on the scale and it read 1.3 grams. How much would you expect 10 playing cards to weigh?

Answer 1

I can't find any multiple choices in the question but my answer would be

If one playing card weighs 1.3 grams, you would expect 10 playing cards to weigh:

10 cards * 1.3 grams/card = 13 grams

So, 10 playing cards would weigh 13 grams in total.
