Wendy had 120 markers.
45 of them were yellow markers and the rest were white markers. After she had given away some yellow markers, the ratio of the number of yellow markers to the number of white markers became 5 : 6. How many yellow markers did she give away?
| |
Yellow |
White |
Total |
| Before |
4x6 =
24 u |
1x6 =
6 u |
5x6 =
30 u |
| Change |
- 19 u |
|
|
| After |
5 u |
6 u |
11 u |
The number of white markers remained unchanged.
LCM of 1 and 6 = 6
Total number of markers at first = 30 u
30 u = 120
1 u = 120 ÷ 30 = 4
Number of yellow markers that she gave away
= 24 u - 5 u
= 19 u
= 19 x 4
= 76
Answer(s):76
