14 of her pens, Kimberly had four times as many pens as Gillian. How many pens did Gillian have at first?

Comparing Kimberly and
Gillian at first |
32 more |

| Before |
12 u |
4 u |
| Change |
|
- 1 u |
| After |
12 u |
3 u |
Comparing Kimberly and
Gillian in the end |
4x3 =
12 u |
1x3 =
3 u |
Number of pens that Gillian had in the end is repeated. Make the number of pens that Gillian had in the end the same. LCM of 1 and 3 is 3.
Number of pens that Kimberly had at first = 12 u
Number of pens that Kimberly had more than Gillian at first
= 12 u - 4 u
= 8 u
8 u = 32
1 u = 32 ÷ 8 = 4
Number of pens that Gillian had at first
= 4 u
= 4 x 4
= 16
Answer(s): 16
