Henry |
Fred |
Chan |
| Before |
9 u |
6 u |
10 u |
| Change |
+ 7.4 u |
+ 0.6 u |
- 8 u |
| After |
16.4 u |
6.6 u |
2 u |
Number of stickers that Chan gave to Henry and Fred
=
45 x 10 u
= 8 u
Number of stickers that Fred received from Chan
=
10100 x 6 u
= 0.6 u
Number of stickers that Henry received from Chan
= 8 u - 0.6 u
= 7.4 u
Number of less stickers that Chan had less than Henry
= 16.4 u - 2 u
= 14.4 u
14.4 u = 144
1 u = 144 ÷ 14.4 = 10
Number of stickers that Henry and Chan had
= 16.4 u + 2 u
= 18.4 u
= 18.4 x 10
= 184
Answer(s): 184
