Please help me :(

First one is 12

Second is 6:8

Third is 3:5

Fourth is 240

Last one is 3:5

Step-by-step explanation:

If you get 2 loaves of bread for 3 cups of raisins and you need 8 loaves then you do 3x4 to get 12

Do 3x2=6 then 4x2=8 so 6:8

Do 3x4=12 and 5x4=20 so 3:5

12/4 is 3 so we know that we divide by 3 720/3 is 240

Same question as #3

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

okay wait before i answer, is this for your points on a graph?
