Given:
10 cousins
1 Jackson cousin
twice as many Lopez cousin as Chen cousin.
The unknown are the number of Lopez cousin and Chen cousin.
Let x represent the number of Chen cousin. Since Lopez cousin is twice the number of Chen cousin, the Lopez cousin is represented by 2x.
1 + 2x + x = 10
3x = 10 - 1
3x = 9
x = 9/3
x = 3 → Number of Chen cousins
2x → 2(3) = 6 → Number of Lopez cousins
There is 1 Jackson cousin, 6 Lopez cousins, and 3 Chen cousins. For a total of 10 cousins.

Answer:
No
Step-by-step explanation:
Write the ratios of erasers to cost (dropping the dollar sign) as fractions:
(number of erasers)/(price): 2/1 and 10/4
The question is if the ratios 2/1 and 10/4 are equivalent.
2/1 = 2
10/4 = 2.5
A proportion is setting two ratios equal. Here, one ratio equals 2, and one ratio equals 2.5.
Since the ratios are not equivalent, the relation is not proportional.
