Total value |
2 x 11 u = 22 u |
50 x 6 u = 300 u |
(a)
Change ratio into units.
Number of $2 notes = 11 u
Number of $50 notes = 6 u
Total number of notes
= 11 u + 6 u
= 17 u
(b)
Difference in the number of notes
= 11 u - 6 u
= 5 u
(c)
Total value of $2 notes
= 11 u x 2
= 22 u
Total value of $50 notes
= 6 u x 50
= 300 u
Total value of notes
= 22 u + 300 u
= 322 u
(d)
Difference in the value of notes
= 300 u - 22 u
= 278 u
Answer(s): (a) 17; (b) 5; (c) 322; (d) 278
