5 x 6 u = 30 u |
50 x 5 u = 250 u |
(a)
Change ratio into units.
Number of $5 notes = 6 u
Number of $50 notes = 5 u
Total number of notes
= 6 u + 5 u
= 11 u
(b)
Difference in the number of notes
= 6 u - 5 u
= 1 u
(c)
Total value of $5 notes
= 6 u x 5
= 30 u
Total value of $50 notes
= 5 u x 50
= 250 u
Total value of notes
= 30 u + 250 u
= 280 u
(d)
Difference in the value of notes
= 250 u - 30 u
= 220 u
Answer(s): (a) 11; (b) 1; (c) 280; (d) 220
