HEEEEELP ME PLEASE ;( (The question is in the picture)

Answer 1

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

Answer 2

Answer:

$\frac{1}{10}$

Step-by-step explanation:

Red

$\frac{2}{5}$

blue

$\frac{1}{8}$

green

$\frac{3}{8}$

first, make denominators same.

*The common LCM we choose is 40*

RED

$\frac{2}{5} \times 8 = \frac{16}{40}$

BLUE

$\frac{1}{8} \times 5 = \frac{5}{40}$

GREEN

$\frac{3}{8} \times 5 = \frac{15}{40}$

Yellow marble:-

RED+GREEN+BLUE =

$\frac{16}{40} + \frac{5}{40} + \frac{15}{40} = \frac{36}{40}$

Yellow marble = total marbles-sum of other marble colours

*note that the total no. marbles are 40*

$\frac{40}{40} - \frac{36}{40} = \frac{4}{40}$

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

$\frac{4}{40} or \frac{1}{10}$
