Jean used
34 of her yellow stickers and
37 of her green stickers to decorate her diary. In the end, she had an equal number of yellow stickers and green stickers left. Given that Jean had a total of 46 yellow and green stickers at first, how many green stickers did she use to decorate the diary?
|
Yellow stickers |
Green stickers |
Before |
4x4 = 16 u |
7x1 = 7 u |
Change |
- 3x4 = - 12 u |
- 3x1 = - 3 u |
After |
1x4 = 4 u |
4x1 = 4 u |
The number of yellow stickers and green stickers in the end is the same. Make the number of yellow stickers and green stickers in the end the same. LCM of 1 and 4 is 4.
Total number of stickers that Jean used to decorate the diary
= 16 u + 7 u
= 23 u
23 u = 46
1 u = 46 ÷ 23 = 2
Number of green stickers that Jean used to decorate the diary
= 3 u
= 3 x 2
= 6
Answer(s): 6
