Total value |
10 x 8 u = 80 u |
50 x 3 u = 150 u |
(a)
Change ratio into units.
Number of $10 notes = 8 u
Number of $50 notes = 3 u
Total number of notes
= 8 u + 3 u
= 11 u
(b)
Difference in the number of notes
= 8 u - 3 u
= 5 u
(c)
Total value of $10 notes
= 8 u x 10
= 80 u
Total value of $50 notes
= 3 u x 50
= 150 u
Total value of notes
= 80 u + 150 u
= 230 u
(d)
Difference in the value of notes
= 150 u - 80 u
= 70 u
Answer(s): (a) 11; (b) 5; (c) 230; (d) 70
