Total value |
10 x 9 u = 90 u |
50 x 5 u = 250 u |
(a)
Change ratio into units.
Number of $10 notes = 9 u
Number of $50 notes = 5 u
Total number of notes
= 9 u + 5 u
= 14 u
(b)
Difference in the number of notes
= 9 u - 5 u
= 4 u
(c)
Total value of $10 notes
= 9 u x 10
= 90 u
Total value of $50 notes
= 5 u x 50
= 250 u
Total value of notes
= 90 u + 250 u
= 340 u
(d)
Difference in the value of notes
= 250 u - 90 u
= 160 u
Answer(s): (a) 14; (b) 4; (c) 340; (d) 160
