Proportion 3514

The brothers collect magnets. Ondrej has 32, 18 he kept. He gave the rest to his brother. In what proportion did they split the magnets? How much more should he give to Ondřej's brother so that the ratio of numbers is 3:5?

Correct answer:

p =  1.2857
x =  6

Step-by-step explanation:

o=18 b=3218=14 p=o/b=18/14=79=172=1.2857

(18-x)=3/5·(32-18+x)

8x = 48


x = 48/8 = 6

x = 6
