Vincent had
19 as many coins as Perry. Perry had thrice as many coins as Rael. If Vincent had 52 coins fewer than Rael,
- how many coins did Vincent have?
- how many coins did they have altogether?
(a)
Number of coins that Vincent had = 1 u
Number of coins that Perry had = 9 u
Number of coins that Rael had = 9 u ÷ 3 = 3 u
Number of coins that Vincent had fewer than Rael
= 3 u - 1 u
= 2 u
2 u = 52
1 u = 52 ÷ 2 = 26
Number of coins that Vincent had
= 1 u
= 26
(b)
Total number of coins that they had
= 1 u + 9 u + 3 u
= 13 u
= 13 x 26
= 338
Answer(s): (a) 26; (b) 338
