(a)
Change ratio into units.
Number of $2 notes = 11 u
Number of $5 notes = 5 u
Total number of notes
= 11 u + 5 u
= 16 u
(b)
Difference in the number of notes
= 11 u - 5 u
= 6 u
(c)
Total value of $2 notes
= 11 u x 2
= 22 u
Total value of $5 notes
= 5 u x 5
= 25 u
Total value of notes
= 22 u + 25 u
= 47 u
(d)
Difference in the value of notes
= 25 u - 22 u
= 3 u
Answer(s): (a) 16; (b) 6; (c) 47; (d) 3
