$50 |
$100 |
Number |
10 u |
9 u |
Total value |
50 x 10 u = 500 u |
100 x 9 u = 900 u |
(a)
Change ratio into units.
Number of $50 notes = 10 u
Number of $100 notes = 9 u
Total number of notes
= 10 u + 9 u
= 19 u
(b)
Difference in the number of notes
= 10 u - 9 u
= 1 u
(c)
Total value of $50 notes
= 10 u x 50
= 500 u
Total value of $100 notes
= 9 u x 100
= 900 u
Total value of notes
= 500 u + 900 u
= 1400 u
(d)
Difference in the value of notes
= 900 u - 500 u
= 400 u
Answer(s): (a) 19; (b) 1; (c) 1400; (d) 400
