(a)
Change ratio into units.
Number of $5 notes = 7 u
Number of $50 notes = 6 u
Total number of notes
= 7 u + 6 u
= 13 u
(b)
Difference in the number of notes
= 7 u - 6 u
= 1 u
(c)
Total value of $5 notes
= 7 u x 5
= 35 u
Total value of $50 notes
= 6 u x 50
= 300 u
Total value of notes
= 35 u + 300 u
= 335 u
(d)
Difference in the value of notes
= 300 u - 35 u
= 265 u
Answer(s): (a) 13; (b) 1; (c) 335; (d) 265
