91 u |
35 u |
130 u |
(b)
LCM of 13 and 7 = 91
Number of stickers that Bryan has = 130 u
(c)
Total number of stickers that the children have
= 91 u + 35 u + 130 u
= 256 u
(d)
Difference in the number of stickers between Bryan and Charlie
= 130 u - 35 u
= 95 u
Answer(s): (a) 1; (b) 130; (c) 256; (d) 95
