(a)
Change ratio into units.
Number of $2 notes = 8 u
Number of $5 notes = 5 u
Total number of notes
= 8 u + 5 u
= 13 u
(b)
Difference in the number of notes
= 8 u - 5 u
= 3 u
(c)
Total value of $2 notes
= 8 u x 2
= 16 u
Total value of $5 notes
= 5 u x 5
= 25 u
Total value of notes
= 16 u + 25 u
= 41 u
(d)
Difference in the value of notes
= 25 u - 16 u
= 9 u
Answer(s): (a) 13; (b) 3; (c) 41; (d) 9
