Ratio help :>

[vapid raptor]

I need help with question b

[fiery lance]

(2/7)x+(5/7)x = 30
(7/7)x = 30
x = 30
red = (2/7)×30 = 60/7 L
yellow = (5/7)×30 = 150/7 L

[vapid raptor]

err

im confused

can you explain

in words

how to work this out

sorry 😅

wait i think i get it

nvm got stuck again

can you explain

sorry for ping didint know you staff

[fiery lance]

x is some constant
the ratio of red to yellow is 2/7 : 5/7
red = (2/7)x
yellow = (5/7)x
and their sum is equal to 30

[vapid raptor]

so 2/7 of 30litres is how many red litres you need

[cloud zinc]

yes and 5/7 of 30l is how many yellow litres is needed

[vapid raptor]
