50 x 7 u = 350 u |
(a)
Change ratio into units.
Number of $5 notes = 10 u
Number of $50 notes = 7 u
Total number of notes
= 10 u + 7 u
= 17 u
(b)
Difference in the number of notes
= 10 u - 7 u
= 3 u
(c)
Total value of $5 notes
= 10 u x 5
= 50 u
Total value of $50 notes
= 7 u x 50
= 350 u
Total value of notes
= 50 u + 350 u
= 400 u
(d)
Difference in the value of notes
= 350 u - 50 u
= 300 u
Answer(s): (a) 17; (b) 3; (c) 400; (d) 300
