2 x 7 u = 14 u |
100 x 2 u = 200 u |
(a)
Change ratio into units.
Number of $2 notes = 7 u
Number of $100 notes = 2 u
Total number of notes
= 7 u + 2 u
= 9 u
(b)
Difference in the number of notes
= 7 u - 2 u
= 5 u
(c)
Total value of $2 notes
= 7 u x 2
= 14 u
Total value of $100 notes
= 2 u x 100
= 200 u
Total value of notes
= 14 u + 200 u
= 214 u
(d)
Difference in the value of notes
= 200 u - 14 u
= 186 u
Answer(s): (a) 9; (b) 5; (c) 214; (d) 186
