Question

Please explain how you got your anwser so I will understand thanks!

Answer 1

Ah the wonders of the metric system and its ease of calculating such percentages! Amazing!

Answer 2

40% is the same as 40/100, and 1 KG is equal to 1000 grams. To figure out what forty percent is, you have to multiply the 1000 grams by 40/100. To make it simpler, 40/100 = 4/10. So, you have 1000 times 4/10 which equals 4000/10 which equals 400. That is how you do it.

To show your work, you would do this:

1 kg = 1000 g

1000 g * 40/100 = 1000g * 4/10 = 4000/10 = 400 g


Hope that helps you.
