Archie had
112 as many erasers as Cody. Cody had twice as many erasers as Fabian. If Archie had 125 erasers fewer than Fabian,
- how many erasers did Archie have?
- how many erasers did they have altogether?
(a)
Number of erasers that Archie had = 1 u
Number of erasers that Cody had = 12 u
Number of erasers that Fabian had = 12 u ÷ 2 = 6 u
Number of erasers that Archie had fewer than Fabian
= 6 u - 1 u
= 5 u
5 u = 125
1 u = 125 ÷ 5 = 25
Number of erasers that Archie had
= 1 u
= 25
(b)
Total number of erasers that they had
= 1 u + 12 u + 6 u
= 19 u
= 19 x 25
= 475
Answer(s): (a) 25; (b) 475
