2 x 5 u = 10 u |
5 x 3 u = 15 u |
(a)
Change ratio into units.
Number of $2 notes = 5 u
Number of $5 notes = 3 u
Total number of notes
= 5 u + 3 u
= 8 u
(b)
Difference in the number of notes
= 5 u - 3 u
= 2 u
(c)
Total value of $2 notes
= 5 u x 2
= 10 u
Total value of $5 notes
= 3 u x 5
= 15 u
Total value of notes
= 10 u + 15 u
= 25 u
(d)
Difference in the value of notes
= 15 u - 10 u
= 5 u
Answer(s): (a) 8; (b) 2; (c) 25; (d) 5
