Book Pages (Find a whole when given a percent and a part in word problems)

The video tutorial explains how to determine the total length of a book when given a percentage and a part of it. Jillian read 60% of a book, which equals 33 pages. By setting up an equation with a variable representing the book's total length, the tutorial demonstrates solving the equation by converting percentages to fractions and using reciprocal multiplication. It also provides hints on simplifying fractions to make calculations easier. The lesson concludes with a summary of the process and the learning outcome.

Jillian read 60% of a book, which is 33 pages. What equation can be set up to find the total number of pages in the book?

• 60% plus the book equals 33 pages

• 60% times the book equals 33 pages

• 60% minus the book equals 33 pages

• 60% of the book equals 33 pages

What is the first step in solving the equation 60% times b equals 33?

• Subtract 60% from both sides

• Convert 60% to a decimal

• Convert 60% to a fraction

• Add 60% to both sides

What is the reciprocal of 60/100 used to solve the equation?

• 6/10

• 10/6

• 60/100

• 100/60

How can the fraction 60/100 be simplified to make calculations easier?

• 6/10

• 3/5

• Both 6/10 and 3/5

• Neither 6/10 nor 3/5
