2 x 6 u = 12 u |
50 x 5 u = 250 u |
(a)
Change ratio into units.
Number of $2 notes = 6 u
Number of $50 notes = 5 u
Total number of notes
= 6 u + 5 u
= 11 u
(b)
Difference in the number of notes
= 6 u - 5 u
= 1 u
(c)
Total value of $2 notes
= 6 u x 2
= 12 u
Total value of $50 notes
= 5 u x 50
= 250 u
Total value of notes
= 12 u + 250 u
= 262 u
(d)
Difference in the value of notes
= 250 u - 12 u
= 238 u
Answer(s): (a) 11; (b) 1; (c) 262; (d) 238
