Reggie had
112 as many erasers as Luke. Luke had thrice as many erasers as Harry. If Reggie had 141 erasers fewer than Harry,
- how many erasers did Reggie have?
- how many erasers did they have altogether?
(a)
Number of erasers that Reggie had = 1 u
Number of erasers that Luke had = 12 u
Number of erasers that Harry had = 12 u ÷ 3 = 4 u
Number of erasers that Reggie had fewer than Harry
= 4 u - 1 u
= 3 u
3 u = 141
1 u = 141 ÷ 3 = 47
Number of erasers that Reggie had
= 1 u
= 47
(b)
Total number of erasers that they had
= 1 u + 12 u + 4 u
= 17 u
= 17 x 47
= 799
Answer(s): (a) 47; (b) 799
