Question

Pls help I dont know how to work it out​

Answer 1

10

Explanation:

let's make the number of red marbles x

so probability of getting red marbles is x/45

so;.

`(x)/(45) = (2)/(9)`

`45 * (x)/(45) = (2)/(9) * 45`

`x = (2)/(9) * 45`

`x = 10`

so the number of red marbles is 10

Answer 2

10 red, 35 blue

Explanation:

2/9 of the 45 marbles must be red.

2/9 * 45 = 10
