Answer:
B) 20
Step-by-step explanation:
Each number in the equation needs to be a whole number, since you can't have 2.5 marbles or something like that.
2/5 of 16 is 6.4
2/5 of 20 is 8
2/5 of 21 is 8.4
2/5 of 26 is 10.4
Even though 20 is the only one that works, if you wanted to be sure it's right, just divide by three after subtracting 8 (the three remaining marbles.)
20-8=12
12÷3=4
The three remaining numbers would be equal and the amount of yellow numbers is a whole number. 20 is correct
