We have a question: Zig wrote four times as many books as Flo. If Zig wrote 60 books, how many books did they write altogether?
And an answer: 75
So how you got the answer?
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.

We have a question: Sabrina is collecting herbs to make a poultice for her grandmother. She needs twice as many basil leaves as sage leaves and 5 fewer sage leaves than verbena leaves. If she needs 12 basil leaves, how many leaves total does she need?
And an answer: 29
So how you got the answer?
First find the number of sage leaves Sabrina needs: 12 basil / 2 basil / sage = 6 sage. Then add 5 to find the total number of verbena leaves she needs: 6 sage + 5 = 11 verbena. Finally, add up all the different leaves to find the total number: 6 sage + 11 verbena + 12 basil = 29 leaves.

We have a question: 1,800 fish swim westward, 3,200 swim eastward, and 500 swim north. What is the number of fish left in the sea, if fishers catch 2/5 of the fish that swam eastward and 3/4 of the fish that swam westward?
And an answer: 2870
So how you got the answer?
When fishers caught 3 / 4 of the fish that swam westward, their total number reduced by 3 / 4 * 1800 fish = 1350. The total number of fish that remained from the total number that swam eastward is 1800 fish - 1350 fish = 450 fish. If fishers caught 2 / 5 of the fish that swam eastward, their total number reduced by 2 / 5 * 3200 fish = 1280 fish. 3200 fish - 1280 fish = 1920 fish remained in the sea from the number that swam westward. The total number of fish in the sea after fishers caught some is 500 of the number that went north + 450 of the fish that swam westward + 1920 of the fish that swam eastward = 2870 fish.
