[tex]\dfrac{1}{1+5}\cdot 60=\dfrac{1}{6}\cdot 60=10[/tex]
There are 10 blue marbles (and 50 green ones).

Answer:

there are 10 blue marbles in the bag

Step-by-step explanation:

A bag contains 60 marbles, some blue and some green. The ratio of blue marbles to green  ones is 1: 5.

Total of 60 marbles

The ration of blue to green is 1:5

1+5 = 6

Total of 6 marbles , 1 is blue

now we make a proportion. Let x be the number of blue marbles in the bag

[tex]\frac{1}{6} = \frac{x}{60}[/tex]

Cross multiply it

[tex]60= 6x[/tex]

Divide both sides by 6

x=10

So there are 10 blue marbles in the bag
