Q: Grady has 20 red numbered cubes and 15 blue numbered cubes. He gives his friend Gage 2/5 of his red numbered cubes and 1/3 of the blue numbered cubes. If Gage had 10 red numbered cubes and 12 blue numbered cubes, find the total number of cubes Gage has?
A: Grady gave 2 / 5 * 20 cubes = 8 of his red numbered cubes to Gage. If Gage initially had 10 red numbered cubes, his total number of red numbered cubes became 10 cubes + 8 cubes = 18 cubes after Grady gave him 8 more. Grady also gave 1 / 3 * 15 cubes = 5 blue numbered cubes to Gage. This increased Gage's total number of blue numbered cubes to 12 cubes + 5 cubes = 17 cubes. The total number of cubes Gage has is now 17 cubes + 18 cubes = 35 cubes. The answer is 35.

Q: Jasmine gets off of work at 4:00 pm. After that, it will take her 30 minutes to commute home, 30 minutes to grocery shop, 10 minutes to pick up the dry cleaning, 20 minutes to pick up the dog from the groomers and 90 minutes to cook dinner when she returns home. What time will she eat dinner?
A: Her errands include a 30 min commute and 30 min grocery shopping, 10 min for dry cleaning and 20 min to grab the dog for a total of 30 + 30 + 10 + 20 = 90 minutes. Her errands took 90 minutes and she has another 90 minutes of cooking for a total of 90 + 90 = 180 minutes of chores / errands. 60 minutes are in 1 hour and she has 180 minutes of work so that's 180 / 60 = 3 hours. She is off of work at 4:00 pm and has 3 hours of errands / chores so she won't be able to eat until 4 + 3 = 7:00 pm. The answer is 7.

Q: Miriam currently has 30 marbles, but she used to have more. Miriam gave her brother 60 marbles, gave her sister twice that amount and gave her friend Savanna three times the amount she currently has. How many marbles did Miriam start with?
A:
If Mariam remains with 30 marbles after giving her brother 60 marbles, she had 30 + 60 = 90 marbles. Mariam's sister receives twice as many marbles as her brother, a total of 2 * 60 = 120 marbles. The total number of marbles before giving any to her brother or sister is 120 + 90 = 210. Savannah is to receive three times as many marbles as Mariam has to remain with, a total of 3 * 30 = 90 marbles. Before giving out any marble, Mariam has 210 + 90 = 300 marbles. The answer is 300.
