Answer:
They both sold $40 worth of cookies.
Step-by-step explanation:
Using multiples the first multiple that 10 and 8 have in common is 40.
10,20,30,40
8,16,24,32,40
0.003 is 1/10 of 0.03.
Just multiply the 0.003 by 10 and you'll get the result. The easiest way to multiply such numbers is to move the dot one position to the right (it would be 2 positions if multiplying by 100, 3 by 1000 etc.). You can do the same with dividing, just remember to move to the left then.
