A librarian put 42 books back on the shelves before lunch. Of the books, 14 were non-fiction. What is the ratio of the number of non-fiction books to the total number of books the librarian put away before lunch?

Non fiction : Total number of books

= 14 : 42

= 1:3

Step-by-step explanation:

Total number of books = 42 books

Non fiction books = 14 books

The ratio of the number of non-fiction books to the total number of books is :

Non fiction : Total number of books

= 14 : 42

Further simplified

= 1:3

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
