Carl had
18 as many erasers as Charlie. Charlie had twice as many erasers as Zane. If Carl had 111 erasers fewer than Zane,
- how many erasers did Carl have?
- how many erasers did they have altogether?
(a)
Number of erasers that Carl had = 1 u
Number of erasers that Charlie had = 8 u
Number of erasers that Zane had = 8 u ÷ 2 = 4 u
Number of erasers that Carl had fewer than Zane
= 4 u - 1 u
= 3 u
3 u = 111
1 u = 111 ÷ 3 = 37
Number of erasers that Carl had
= 1 u
= 37
(b)
Total number of erasers that they had
= 1 u + 8 u + 4 u
= 13 u
= 13 x 37
= 481
Answer(s): (a) 37; (b) 481
