a. mg b. g c. kg
2. What is a simpler way to write 12d+7d+53d+2d? (add together all the numbers with hdh keep the hdh after the total)
My Guesses:

2. I have two answers:
I am pretty sure it is: 24d5
OR
my other answer (I do not think this one is write) is: 18d+5
Please help me! Thank you so much.

a. Yes, kg is more convenient, but you really could use any of those units.
b. 18d+5 is the correct answer

How did u figure #2 out?

12d, 7d, 2d and 3d add up to +18d.
The +5 doesn't get added to anything else.
