Winnie has 2 times as many pens as Vanessa. Vanessa has
67 as many pens as Anna. If the three of them have a total of 275 pens, how many pens does Anna have?
Winnie |
Vanessa |
Anna |
2x6 |
1x6 |
|
|
6x1 |
7x1 |
12 u |
6 u |
7 u |
The number of pens that Vanessa has is repeated. Make the number of pens that Vanessa has the same. LCM of 1 and 6 is 6.
Total number of pens that the three of them have
= 12 u + 6 u + 7 u
= 25 u
25 u = 275
1 u = 275 ÷ 25 = 11
Number of pens that Anna has
= 7 u
= 7 x 11
= 77
Answer(s): 77
