Total value |
10 x 5 u = 50 u |
50 x 4 u = 200 u |
(a)
Change ratio into units.
Number of $10 notes = 5 u
Number of $50 notes = 4 u
Total number of notes
= 5 u + 4 u
= 9 u
(b)
Difference in the number of notes
= 5 u - 4 u
= 1 u
(c)
Total value of $10 notes
= 5 u x 10
= 50 u
Total value of $50 notes
= 4 u x 50
= 200 u
Total value of notes
= 50 u + 200 u
= 250 u
(d)
Difference in the value of notes
= 200 u - 50 u
= 150 u
Answer(s): (a) 9; (b) 1; (c) 250; (d) 150
