Texas Go Math Grade 4 Lesson 5.3 Answer Key Subtract Fractions Using Models (1)
A rover needs to travel \(\frac{5}{8}\) mile to reach its destination. It has already traveled \(\frac{3}{8}\) mile. How much farther does the rover need to travel?
Answer:

Compare fractions to find the difference.

STEP 1 Shade the model.
Shade the model to show the total distance
Then shade the model to show how much distance the rover has already covered.
Texas Go Math Grade 4 Lesson 5.3 Answer Key Subtract Fractions Using Models (2)
Answer:
Texas Go Math Grade 4 Lesson 5.3 Answer Key Subtract Fractions Using Models (3)
Explanation:
\(\frac{5}{8}\) – \(\frac{3}{8}\) = \(\frac{2}{8}\)

STEP 2 Write the difference.
\(\frac{5}{8}-\frac{3}{8}\) = \(\frac{}{8}\)
So, the rover needs to travel __________ mile farther.
Answer:
\(\frac{5}{8}-\frac{3}{8}\) = \(\frac{2}{8}\)
So, the rover needs to travel \(\frac{2}{8}\) mile farther.

Another Way Use fraction strips.

Use five \(\frac{1}{8}\)-size parts to model the whole distance.
How many \(\frac{1}{8}\)-size parts should you cross out to
model the distance the rover has traveled? ___________
How many \(\frac{1}{8}\)-size parts are left? ___________
Write the difference.
\(\frac{5}{8}\) – __________ = _________
Answer:
How many \(\frac{1}{8}\)-size parts should you cross out to
model the distance the rover has traveled? 3 we have to cross out.
How many \(\frac{1}{8}\)-size parts are left? 2 are left
Write the difference.
\(\frac{5}{8}\) – \(\frac{3}{8}\) = \(\frac{2}{8}\)
