(a)
Change ratio into units.
Number of $2 notes = 4 u
Number of $50 notes = 3 u
Total number of notes
= 4 u + 3 u
= 7 u
(b)
Difference in the number of notes
= 4 u - 3 u
= 1 u
(c)
Total value of $2 notes
= 4 u x 2
= 8 u
Total value of $50 notes
= 3 u x 50
= 150 u
Total value of notes
= 8 u + 150 u
= 158 u
(d)
Difference in the value of notes
= 150 u - 8 u
= 142 u
Answer(s): (a) 7; (b) 1; (c) 158; (d) 142
