Min has 3 times as many pens as Dana. Dana has
35 as many pens as Natalie. If the three of them have a total of 34 pens, how many pens does Natalie have?
| Min |
Dana |
Natalie |
| 3x3 |
1x3 |
|
| |
3x1 |
5x1 |
| 9 u |
3 u |
5 u |
The number of pens that Dana has is repeated. Make the number of pens that Dana has the same. LCM of 1 and 3 is 3.
Total number of pens that the three of them have
= 9 u + 3 u + 5 u
= 17 u
17 u = 34
1 u = 34 ÷ 17 = 2
Number of pens that Natalie has
= 5 u
= 5 x 2
= 10
Answer(s): 10
