5 x 11 u = 55 u |
100 x 7 u = 700 u |
(a)
Change ratio into units.
Number of $5 notes = 11 u
Number of $100 notes = 7 u
Total number of notes
= 11 u + 7 u
= 18 u
(b)
Difference in the number of notes
= 11 u - 7 u
= 4 u
(c)
Total value of $5 notes
= 11 u x 5
= 55 u
Total value of $100 notes
= 7 u x 100
= 700 u
Total value of notes
= 55 u + 700 u
= 755 u
(d)
Difference in the value of notes
= 700 u - 55 u
= 645 u
Answer(s): (a) 18; (b) 4; (c) 755; (d) 645
