Xandra has 2 times as many pens as Fiona. Fiona has
58 as many pens as Pamela. If the three of them have a total of 69 pens, how many pens does Pamela have?
Xandra |
Fiona |
Pamela |
2x5 |
1x5 |
|
|
5x1 |
8x1 |
10 u |
5 u |
8 u |
The number of pens that Fiona has is repeated. Make the number of pens that Fiona has the same. LCM of 1 and 5 is 5.
Total number of pens that the three of them have
= 10 u + 5 u + 8 u
= 23 u
23 u = 69
1 u = 69 ÷ 23 = 3
Number of pens that Pamela has
= 8 u
= 8 x 3
= 24
Answer(s): 24
