Question

HEEEEELP ME PLEASE ;(

(The question is in the picture)

Answer 1

`(1)/(10)`

Explanation:

Red

`(2)/(5)`

blue

`(1)/(8)`

green

`(3)/(8)`

first, make denominators same.

*The common LCM we choose is 40*

RED

`(2)/(5) * 8 = (16)/(40)`

BLUE

`(1)/(8) * 5 = (5)/(40)`

GREEN

`(3)/(8) * 5 = (15)/(40)`

Yellow marble:-

RED+GREEN+BLUE =

`(16)/(40) + (5)/(40) + (15)/(40) = (36)/(40)`

Yellow marble = total marbles-sum of other marble colours

*note that the total no. marbles are 40*

`(40)/(40) - (36)/(40) = (4)/(40)`

*you can leave it in this form or you can simplify it*

`(4)/(40) or (1)/(10)`

Answer 2

1/10 you find a common denominator and add them together which is 36 and simplify it down
