Ben had
18 as many pens as Tim. Tim had twice as many pens as Zane. If Ben had 126 pens fewer than Zane,
- how many pens did Ben have?
- how many pens did they have altogether?
(a)
Number of pens that Ben had = 1 u
Number of pens that Tim had = 8 u
Number of pens that Zane had = 8 u ÷ 2 = 4 u
Number of pens that Ben had fewer than Zane
= 4 u - 1 u
= 3 u
3 u = 126
1 u = 126 ÷ 3 = 42
Number of pens that Ben had
= 1 u
= 42
(b)
Total number of pens that they had
= 1 u + 8 u + 4 u
= 13 u
= 13 x 42
= 546
Answer(s): (a) 42; (b) 546
