$50 |
$100 |
Number |
10 u |
7 u |
Total value |
50 x 10 u = 500 u |
100 x 7 u = 700 u |
(a)
Change ratio into units.
Number of $50 notes = 10 u
Number of $100 notes = 7 u
Total number of notes
= 10 u + 7 u
= 17 u
(b)
Difference in the number of notes
= 10 u - 7 u
= 3 u
(c)
Total value of $50 notes
= 10 u x 50
= 500 u
Total value of $100 notes
= 7 u x 100
= 700 u
Total value of notes
= 500 u + 700 u
= 1200 u
(d)
Difference in the value of notes
= 700 u - 500 u
= 200 u
Answer(s): (a) 17; (b) 3; (c) 1200; (d) 200
