Opens on Chapter 15’s example: a $240 refund shared 3 : 5 by what each person paid.

Enter your numbers, then press Calculate.
From the book, Chapter 15. 3 : 5 is 8 parts, so one part of $240 is $30: $90 and $150, and Inez’s share is 3/8 of the whole. Concrete 1 : 2 : 3 in 12 buckets: 2, 4 and 6. Lemonade 1 : 5 in 12 cups: 2 and 10. Cats to dogs 2 : 3 among 40: 16 cats (40%), 24 dogs. 1,920 : 1,080 simplifies to 16 : 9.
