Zig wrote four times as many books as Flo. If Zig wrote 60 books, how many books did they write altogether? Give the rationale and then the answer.
Let's think step by step. If Zig wrote 60 books, four times as many books as Flo, Flo wrote 60 / 4 = 15 books. Together, they wrote 60 + 15 = 75 books.. The answer is: 75.

Marge planted 23 seeds in her garden. Five of the seeds never grew into plants. A third of the remaining seeds grew, but the plants were eaten by squirrels and rabbits. A third of the number of uneaten plants were strangled by weeds. Marge pulled two weeds, but liked the flowers on one weed and let the plant grow as part of her garden. How many plants did Marge end up with? Give the rationale and then the answer.
Let's think step by step. Marge had 23 - 5 = 18 seeds grow into plants. Rabbits ate 18 / 3 = 6 plants. There were 18 - 6 = 12 plants left. Weeds strangled 12 / 3 = 4 plants. She had 12 - 4 = 8 plants left. Marge kept 1 weed, so she ended up with 8 + 1 = 9 plants.. The answer is: 9.

Cary is 72 inches tall. Her younger brother Bill is half her height, and her younger sister Jan is 6 inches taller than Bill. How tall is Jan? Give the rationale and then the answer.
Let's think step by step. First find Bill's height by dividing Cary's height by 2: 72 inches / 2 = 36 inches. Then add six inches to find Jan's height: 36 inches + 6 inches = 42 inches.. The answer is: 42.
