Narcisse and aristide have numbers of arcade tokens in the ratio 7 : 3, respectively. narcisse gives aristide some of his tokens, and the new ratio is 6 : 5. what is the least number of tokens that narcisse could have given to aristide?

The least number of tokens that Narcisse could have given to Aristide are: 3

Step-by-step explanation:

Narcisse gives an "X" amount of the 7 tokens he initially had to aristide, which are added up to the 3 tokens that Aristide had. After that transaction the ratio changes from 7: 3 to 6: 5

42-6X=5X+15

33=11X

X=3

i believe it's a.

i'm not sure on this one, most likely correct.
