Answer:
9 students play sodoku and chess.
Step-by-step explanation:
What do we have?
2/3; play sudoku
3/8; play chess
24; students total
Find a common denominator for the fractions:
2/3x8/8
3/8x3/3
Now we have:
16/24
9/24
This also makes sense because we have a total of 24 students, now we want to know how many of them play sodoku AND chess; which was originally 3/8.
It's 9 students!
