Q: James hurt himself exercising. The pain subsided after 3 days, but he knew that the injury would take at least 5 times that long to fully heal. After that, he wanted to wait another 3 days before he started working out again. If he wants to wait 3 weeks after that to start lifting heavy again, how long until he can lift heavy again?
A: The injury would be fully healed after 3 * 5 = 15 days. So he would start exercising again in 15 + 3 = 18 days. He would then wait for 3 * 7 = 21 more days to start lifting heavy again. That means he needs to wait 18 + 21 = 39 days. The answer is 39.

Q: The ratio of boys to girls in a family is 5:7. The total number of children in the family is 180. If the boys are given $3900 to share, how much money does each boy receive?
A:
The total ratio representing the number of children in the family is 5 + 7 = 12. From the total ratio of children in the family, 5 / 12 represent the number of boys, meaning that the number of boys in the family is 5 / 12 * 180 = 75. If the boys are given $3900 to share, each boy receives $3900 / 75 = $52. The answer is 52.
