Jawad has seven rocks. The total weight of all seven rocs is 5 kilograms. 6 of the rocks each have a weight of 720 grams. Work out the weight, in grams, of the other rock? mathswatch

680 grams.

Step-by-step explanation:

So, it's telling us to calculate the weight, in grams, of the other rock.

So firstly,

6 of the rocks EACH have a weight of 720 grams.

So, 6 x 720 = 4320

Now save 4320 for later.

Next, we need to convert the 5 kilograms into grams.

So, 5 x 1000 = 5000

now do, 5000 - 4320 = 680.

Your final answer would then be = 680g

I hope this helped. I apologise for the late reply.

If not, please reply so I can simplify my explanations.
