(a)
Change ratio into units.
Number of $2 notes = 7 u
Number of $50 notes = 2 u
Total number of notes
= 7 u + 2 u
= 9 u
(b)
Difference in the number of notes
= 7 u - 2 u
= 5 u
(c)
Total value of $2 notes
= 7 u x 2
= 14 u
Total value of $50 notes
= 2 u x 50
= 100 u
Total value of notes
= 14 u + 100 u
= 114 u
(d)
Difference in the value of notes
= 100 u - 14 u
= 86 u
