Seth had
110 as many erasers as Warren. Warren had twice as many erasers as Liam. If Seth had 124 erasers fewer than Liam,
- how many erasers did Seth have?
- how many erasers did they have altogether?
(a)
Number of erasers that Seth had = 1 u
Number of erasers that Warren had = 10 u
Number of erasers that Liam had = 10 u ÷ 2 = 5 u
Number of erasers that Seth had fewer than Liam
= 5 u - 1 u
= 4 u
4 u = 124
1 u = 124 ÷ 4 = 31
Number of erasers that Seth had
= 1 u
= 31
(b)
Total number of erasers that they had
= 1 u + 10 u + 5 u
= 16 u
= 16 x 31
= 496
Answer(s): (a) 31; (b) 496
