What is the result of adding 4/6 and 1/6 in the second example problem?

• 1 and 1/6

• 1/6

• 2/6

• 5/6

How can a number line be used to solve a fraction problem?

• By ignoring it completely

• By drawing random lines

• By marking fractions on the line and moving forwards or backwards

• By using it to multiply fractions

What is the final answer in the complex problem involving 10/15, 7/15, 12/15, and 1/15?

• 2

• 1

• 3

• 4

What is the benefit of students exploring various methods to solve problems?
