Answer:
57.5 marbles rounding to 58 if you do not have partial marbles
Step-by-step explanation:
The number of marbles is equal to the percent of the marbles times the total number of marbles
23 = 40% total marbles
Change to decimal form
23 = .40 M
Divide by .40
23/.40 = .40M/.40
57.5 = M
This question is odd since you can't have part of a marble
I would round up and have 58 marbles
58 *.40 = 23.2 marbles
3,000 = 3 x 10 x 10 x 10 = 3 * 10^3
--------------
10^3 * 3 * (640)
= 10^3 * 3 * (600 + 40)
= 10^3 * (1800 + 120)
= 10^3 * 1920
= 1,920,000
