Answer 1

Ok this is pretty simple hun, all you have to do if you encounter another exercise like this is see how many are of each colores marble and do it as a fraction with the total of numbers! Let me show you!

Explanation:

there are 30 beads in total (this will be our denominator in our fraction)

Because there are equal numbers of blue, orange and green we divide 30 into 3

30/3 = 10

So there are. 10 of each color.

Next we add the number of blue and green beads so

10 + 10 = 20 (that is our numerator)

Now we do a fraction

20/30 = 2/3 cause we divided both numbers by 10

Making the answer B. 2/3

Answer 2

I think that the answer is 2/3 I might be wrong tho
