Answer:

½ × ⅔ × 5/1

• ½ × ⅔ × 5/1 (reduce the numbers with the greatest common factor 2)
• ⅓ × 5/1 (multiply the fractions)
• = 5/3

⅚ × 4/9 × 4/1

• ⅚ × 4/9 × 4/1 (reduce the numbers with the greatest common factor 2)
• 5/3 × 2/9 × 4/1 (multiply the fractions)
• = 40/27

3/7 × ⅘

• 3/7 × ⅘ (to multiply the fractions, multiply the numerators and dominators separately)
• 3 × 4 / 7 × 5 (multiply the numbers)
• 3 × 4 / 7 × 5 = 12
• 12 / 7 × 5 = 12/35
• = 12/35

8/9 × ⅓

• 8/9 × ⅓ (to multiply the fractions, multiply the numerators and dominators separately)
• 8 × 1 / 9 × 3 (any expression multiplied by 1 remains the same)
• 8 / 9 × 3 = 8 × 1 / 9 × 3
• = 8/27

⅘ × ⅜

• ⅘ × ⅜ (reduce the numbers with the greatest common factor 4)
• ⅕ × 3/2 (multiply the fractions)
• = 3/10
