Total value |
2 x 11 u = 22 u |
100 x 5 u = 500 u |
(a)
Change ratio into units.
Number of $2 notes = 11 u
Number of $100 notes = 5 u
Total number of notes
= 11 u + 5 u
= 16 u
(b)
Difference in the number of notes
= 11 u - 5 u
= 6 u
(c)
Total value of $2 notes
= 11 u x 2
= 22 u
Total value of $100 notes
= 5 u x 100
= 500 u
Total value of notes
= 22 u + 500 u
= 522 u
(d)
Difference in the value of notes
= 500 u - 22 u
= 478 u
Answer(s): (a) 16; (b) 6; (c) 522; (d) 478
