Natalie has 2 times as many pencils as Julie. Julie has
37 as many pencils as Jade. If the three of them have a total of 192 pencils, how many pencils does Natalie have?
Natalie |
Julie |
Jade |
2x3 |
1x3 |
|
|
3x1 |
7x1 |
6 u |
3 u |
7 u |
The number of pencils that Julie has is repeated. Make the number of pencils that Julie has the same. LCM of 1 and 3 is 3.
Total number of pencils that the three of them have
= 6 u + 3 u + 7 u
= 16 u
16 u = 192
1 u = 192 ÷ 16 = 12
Number of pencils that Natalie has
= 6 u
= 6 x 12
= 72
Answer(s): 72
