Total value |
5 x 6 u = 30 u |
100 x 1 u = 100 u |
(a)
Change ratio into units.
Number of $5 notes = 6 u
Number of $100 notes = 1 u
Total number of notes
= 6 u + 1 u
= 7 u
(b)
Difference in the number of notes
= 6 u - 1 u
= 5 u
(c)
Total value of $5 notes
= 6 u x 5
= 30 u
Total value of $100 notes
= 1 u x 100
= 100 u
Total value of notes
= 30 u + 100 u
= 130 u
(d)
Difference in the value of notes
= 100 u - 30 u
= 70 u
Answer(s): (a) 7; (b) 5; (c) 130; (d) 70
