Answer:
3
Step-by-step explanation:
6 cups require 2 cups
9 cups require-------x
Cross multiplication
9x2 = 6x
18 = 6x
x= 3
Another way to think about:
6 + half of 6 = 9
Then
2+ and half of 2 = 3
6 is 3 times more than 2
9 is 3 times bigger than 3
Just work this problem out backwards. First write out an equation.
(x+4)•3=30
Now solve :
(x+4)•3=30
3x+12=30
-12 -12
3x=18
/3 /3
x=6
Your answer is 6!
