The ratio is 6:18 and you are trying to find out what are blue. You divide 240 by 6 and get 40. You then multiply 40 x 18 and get 720.
That is correct, the answer is correct
(3+3+3+3=12) (3x4=12)
(-3) +(-3)+ (-3)+ (-3)= (-12) (-3x4=-12)
The answer is 125. Just for you to understand all you have to do is 20 *____ =625 in this case 20*125=625 :)
