I'm helping my son with a long list of math problems. At the end I was able to help him with all of them except for three questions.
I would appreciate your guidance in solving these:
1. In a class 5/12 were girls. If there were 4 fewer girls than boys, how many were in the class?
2. 12 exercise books and a textbook cost $56. 6 exercise books and 2 text books $58. How many dollars was each text book?
3. Alison shared 56 stamps with Julia so that she had 3 times as many as Julia. How many stamps did Julia received?
Many thanks in advance.
