Question

Answer 1

Answer:

45 green marbles

Step-by-step explanation:

Green : Blue : Red = 3 : 7 : 5

Fraction of green marbles = $\frac{3}{3+7+5}=\frac{3}{15}$

Total marbles = 225

Number of green marbles = $\frac{3}{15}*225$

                                           = 3 * 15

                                           = 45
