If the mass of a material is 49 grams and the volume of the material is 7 cm^3, what would the density of the material be?

The equation for density is:


To help you remember - my teacher told us to remember "We ♡ density," and the heart stands for , or . Cheesy, but it works!

Back to the problem:
We know the mass if 49g and the volume is 7 , so plug these values into the equation for density:


The density is 7 g/

Find the highest common factor 
12 = 1, 2, 3, 4, 6, 12
24 = 1, 2, 3, 4, 6, 8, 12, 24
28 = 1, 2, 4, 7, 14, 28
4 bags is needed 
3 apple, 6 blueberry, 7 banana in each bag
(3 x 4 = 12 apple) (6 x 4 - 24 blueberry) (7 x 4 = 28 banana)
