1 u |
Total value |
2 x 10 u = 20 u |
50 x 1 u = 50 u |
(a)
Change ratio into units.
Number of $2 notes = 10 u
Number of $50 notes = 1 u
Total number of notes
= 10 u + 1 u
= 11 u
(b)
Difference in the number of notes
= 10 u - 1 u
= 9 u
(c)
Total value of $2 notes
= 10 u x 2
= 20 u
Total value of $50 notes
= 1 u x 50
= 50 u
Total value of notes
= 20 u + 50 u
= 70 u
(d)
Difference in the value of notes
= 50 u - 20 u
= 30 u
Answer(s): (a) 11; (b) 9; (c) 70; (d) 30
