Vacation in the Island (Use number lines to solve word problems involving the addition of fractions with like and unlike

Jeremy and Kathy are on a sightseeing trip on a small island. The video tutorial explains how to calculate the total walking distance using number lines to represent fractions. It demonstrates adding fractions with unlike denominators by finding a common denominator, resulting in a total distance of 9/12 kilometers. The lesson focuses on using number lines to visualize and add fractions effectively.

What is the walking distance from the hotel to the downtown area?

• 2/6 kilometer

• 1/4 kilometer

• 1/6 kilometer

• 3/6 kilometer

How is the first number line divided to represent the distance from the hotel to downtown?

• Into 4 equal parts

• Into 6 equal parts

• Into 12 equal parts

• Into 3 equal parts

What is the sum of the distances from the hotel to downtown and from downtown to the lighthouse?

• 3/6

• 4/6

• 2/6

• 1/6

Why can't the distances 3/6 and 1/4 be directly added?

• They are not fractions

• They have different denominators

• They have different numerators

• They are not on the same number line

What is the common denominator used to add 3/6 and 1/4?

• 12

• 10

• 8

• 6

How many parts does the total distance extend on the number line after finding a common denominator?

• 15 parts

• 9 parts

• 6 parts

• 12 parts

What is the total distance Jeremy and Kathy will walk today?

• 7/12 kilometer

• 9/12 kilometer

• 8/12 kilometer

• 10/12 kilometer
