Andy has a collection of blue and green marbles. the number of blue marbles is three times the number of green marbles. if there are 66 blue marbles in his collection how many green marbles are there

Number of green marbles in the collection is 22

Step-by-step explanation:

Andy has a collection of blue and green marbles.

Let x = number of blue marbles in the collection.

Let y = number of green marbles in the collection.

The number of blue marbles is three times the number of green marbles. This means

b =3y

If there are 66 blue marbles in his collection, that means that x = 66

If number of blue marbles is 66, then

Number of green marbles in the collection would be

3y = 66

y = 66/3 = 22 green marbles

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
