The number of boys that left the camp doesn't actually matter. since 12 girls left the camp, 8 are left and now you have to find 3/4 of 8 which is 6. since 4 boys left camp you add that to 6 which means your answer is 10 tell me if you have any questions
Don’t understand what your asking in the first one. Choosing a vowel out of the word counting would be 3/8. And picking a consonant out of the word prime would be 3/5.
