Bryan had
12 as many cards as Howard. Howard had
23 as many cards as Diana. After Bryan and Diana gave 28 cards to Howard, Howard had four times as many cards as Bryan. Diana then had the same number of cards as Howard.
- What was the ratio of the number of cards Bryan had to the number of cards Diana had in the beginning? Answer in simplest form.
- How many cards did Howard have in the end?

(a)
The number of cards that Howard is repeated.
Ratio of the number of cards that Bryan had to the number of cards that Diana had in the beginning = 1 : 3

Total |
Before |
1x3 = 3 u |
2x3 = 6 u |
3x3 = 9 u |
6x3 = 18 u |
Change |
- 28 |
+ 56 |
- 28 |
|
After |
1x2 = 2 u |
4x2 = 8 u |
4x2 = 8 u |
9x2 = 18 u |
The total number of cards at first and in the end remains unchanged. Make the total number of cards the same. LCM of 6 and 9 is 18.
Number of cards that Howard received from Bryan and Diana
= 2 x 28
= 56
Number of cards that Howard received from Bryan and Diana
= 2 x 1 u
= 2 u
2 u = 28
1 u = 28 ÷ 2 = 14
Number of cards that Ashley had in the end
= 8 u
= 8 x 14
= 112
Answer(s): (a) 1 : 3; (b) 112
