13x5 |
10x5 |
78 u |
65 u |
50 u |
(b)
LCM of 5 and 13 = 65
Number of stickers that Bryan has = 65 u
(c)
Total number of stickers that the children have
= 78 u + 65 u + 50 u
= 193 u
(d)
Difference in the number of stickers between Bryan and Charlie
= 65 u - 50 u
= 15 u
Answer(s): (a) 2; (b) 65; (c) 193; (d) 15
