(a)
Change ratio into units.
Number of $5 notes = 11 u
Number of $50 notes = 9 u
Total number of notes
= 11 u + 9 u
= 20 u
(b)
Difference in the number of notes
= 11 u - 9 u
= 2 u
(c)
Total value of $5 notes
= 11 u x 5
= 55 u
Total value of $50 notes
= 9 u x 50
= 450 u
Total value of notes
= 55 u + 450 u
= 505 u
(d)
Difference in the value of notes
= 450 u - 55 u
= 395 u
Answer(s): (a) 20; (b) 2; (c) 505; (d) 395
