Sara has 5 red marble, 3 green marbles and 2 blue marbles. What fraction of the marbles are green?
Answer: 3/10
Explanation
To find the fraction of green marbles, we need to calculate the total number of marbles first.
Sara has:
- 5 red marbles
- 3 green marbles
- 2 blue marbles
Total marbles = 5 (red) + 3 (green) + 2 (blue) = 10 marbles
Next, we determine the fraction of green marbles out of the total marbles:
Fraction of green marbles = Number of green marbles / Total number of marbles
Fraction of green marbles = 3 / 10
