$10 |
$100 |
Number |
11 u |
5 u |
Total value |
10 x 11 u = 110 u |
100 x 5 u = 500 u |
(a)
Change ratio into units.
Number of $10 notes = 11 u
Number of $100 notes = 5 u
Total number of notes
= 11 u + 5 u
= 16 u
(b)
Difference in the number of notes
= 11 u - 5 u
= 6 u
(c)
Total value of $10 notes
= 11 u x 10
= 110 u
Total value of $100 notes
= 5 u x 100
= 500 u
Total value of notes
= 110 u + 500 u
= 610 u
(d)
Difference in the value of notes
= 500 u - 110 u
= 390 u
Answer(s): (a) 16; (b) 6; (c) 610; (d) 390
