(a)
Change ratio into units.
Number of $2 notes = 9 u
Number of $50 notes = 2 u
Total number of notes
= 9 u + 2 u
= 11 u
(b)
Difference in the number of notes
= 9 u - 2 u
= 7 u
(c)
Total value of $2 notes
= 9 u x 2
= 18 u
Total value of $50 notes
= 2 u x 50
= 100 u
Total value of notes
= 18 u + 100 u
= 118 u
(d)
Difference in the value of notes
= 100 u - 18 u
= 82 u
