Hazel has 2 times as many pens as Xylia. Xylia has
57 as many pens as Irene. If the three of them have a total of 242 pens, how many pens does Hazel have?
Hazel |
Xylia |
Irene |
2x5 |
1x5 |
|
|
5x1 |
7x1 |
10 u |
5 u |
7 u |
The number of pens that Xylia has is repeated. Make the number of pens that Xylia has the same. LCM of 1 and 5 is 5.
Total number of pens that the three of them have
= 10 u + 5 u + 7 u
= 22 u
22 u = 242
1 u = 242 ÷ 22 = 11
Number of pens that Hazel has
= 10 u
= 10 x 11
= 110
Answer(s): 110
