Question

Sam is making an aquaponics garden. He needs 2.3 dkg of granite. He has 460 g. How much more does he need? Explain your answer with your work. ​

Answer 1

Explanation:

He needs 2.3 dkg

dkg is a unit of mass and represents dekagrams.

The relationship between dkg and g is given as;

1 dkg = 10g

This means he needs 2.3 * 10 = 23 g of graphite.

Since he already has 460g of graphite, he doesn't need any additional graphite.
