An ice cream vendor has 50 chocolate-flavored ice creams and 54 mango-flavored ice creams in his cart. If he sold 3/5 of the chocolate-flavored ice creams and 2/3 of the mango-flavored ice creams, how many total ice creams were not sold?
Let's think: There were a total of 50 + 54 = 104 ice creams. There were 50 x 3 / 5 = 30 chocolate - flavored ice creams sold. There were 54 x 2 / 3 = 36 mango - flavored ice creams sold. A total of 30 + 36 = 66 ice creams were sold. So, 104 - 66 = 38 ice creams were not sold.. The answer is: 38.

Kendra baked cookies for her family. Each batch contains 12 cookies. His family has 4 total people. She made three batches. Each cookie contains 2 chocolate chips. How many chips does each family member eat if they all get the same number of cookies?
Let's think: She made 36 cookies because 12 x 3 = 36. These contain 72 chocolate chips because 36 x 2 = 72. They each get to eat 18 chocolate chips because 72 / 4 = 18.. The answer is: 18.

In five years Sam will be 3 times as old as Drew. If Drew is currently 12 years old, how old is Sam?
Let's think: In five years Drew will be 12 + 5 = 17 years old. In five years Sam will be 3(17) = 51 years old. Sam is currently 51 - 5 = 46 years old.. The answer is: 46.

Rajesh walked 10 kilometers less than 4 times the distance that Hiro walked. Together they walked 25 kilometers. How many kilometers did Rajesh walk?
Let's think:
Let H = distance Hiro walked. 4H - 10 = distance Rajesh walked. H + 4H - 10 = 25. 5H - 10 = 25. 5H = 35. Hiro walked 7 km so Rajesh walked 4(7) - 10 = 18 km. Rajesh walked 18 kilometers.. The answer is: 18.
