In this video, I explained how to solve a problem involving fractions. I demonstrated how to represent 6 tenths (0.6) divided by 2 as a fraction, identifying the correct model that shows 60 out of 100 units shaded, which when divided by 2 results in 30 out of 100 units, or 0.3. I walked through the process of counting the shaded units in different models to determine which one correctly represents the required fraction division.

In this video, I explained how to add two fractions with different denominators. I demonstrated the process using the example of 2/8 plus 1/3. First, I found the least common multiple of the denominators (8 and 3), which is 24. Then, I converted both fractions to have a common denominator of 24. After adding the numerators (6 + 8 = 14), I simplified the fraction by dividing both the numerator and denominator by 2, resulting in the answer 7/12.

I explained how to add fractions with different denominators. I demonstrated using candy bars that one-half plus three-fourths requires finding a common denominator of eight. I showed that this equals ten-eighths, which simplifies to one and one-fourth.

I demonstrated how to subtract mixed numbers by solving 7 and 1 half minus 4 and 3 fourths. I converted both mixed numbers to improper fractions, found common denominators, subtracted them, and converted the result back to the mixed number 2 and 3 fourths. I emphasized that practice makes these fraction operations easier over time.
