Question

pls help I dont know how to work it out​

Answer 1

Answer:

10 red, 35 blue

Step-by-step explanation:

2/9 of the 45 marbles must be red.

2/9 * 45 = 10

Answer 2

Answer:

10

Step-by-step explanation:

let's make the number of red marbles x

so probability of getting red marbles is x/45

so;.

$\frac{x}{45} = \frac{2}{9}$

$45 \times \frac{x}{45} = \frac{2}{9} \times 45$

$x = \frac{2}{9} \times 45$

$x = 10$

so the number of red marbles is 10
