Fraction Decomposition and Operations

The video tutorial covers various math problems involving fractions. It begins with matching equivalent expressions, followed by calculating the fraction of students who did not attend a field trip. The next problem involves determining the fraction of a garden planted with flowers. The tutorial then explores decomposing fractions and identifying true or false equations. Finally, it demonstrates subtracting mixed numbers to find the length of ribbon used.

If 7/8 of Riley's garden is planted, and 2/8 is vegetables, what fraction is flowers?

• 6/8

• 3/8

• 4/8

• 5/8

How much of Riley's garden is not planted if 7/8 is planted?

• 3/8

• 2/8

• 4/8

• 1/8

Which of the following is a way to decompose 7/8?

• 4/8 + 3/8

• 2/8 + 2/8 + 2/8

• 1/8 + 1/8 + 5/8

• 3/8 + 3/8

Which expression is not a valid decomposition of 7/8?

• 3/8 + 3/8

• 1/8 + 1/8 + 5/8

• 1/8 + 2/8 + 3/8 + 1/8

• 1/8 + 3/8 + 3/8

Which equation is not true when 4/12 is the missing number?

• 3/12 + 4/12 = 7/12

• 1 5/12 - 4/12 = 1 1/12

• 16/12 - 4/12 = 1

• 1 1/12 + 4/12 = 5/12
