Hazel had 90 markers.
45 of them were yellow markers and the rest were gold markers. After she had given away some yellow markers, the ratio of the number of yellow markers to the number of gold markers became 5 : 6. How many markers did she have in the end?
| |
Yellow |
Gold |
Total |
| Before |
4x6 =
24 u |
1x6 =
6 u |
5x6 =
30 u |
| Change |
- 19 u |
|
|
| After |
5 u |
6 u |
11 u |
The number of gold markers remained unchanged.
LCM of 1 and 6 = 6
Total number of markers at first = 30 u
30 u = 90
1 u = 90 ÷ 30 = 3
Number of markers that Hazel had in the end
= 5 u + 6 u
= 11 u
= 11 x 3
= 33
Answer(s):33
