Answer 3

To solve the expression 9 2/5 + 3/8 - 4 3/20, we can follow these steps:

Step 1: Convert mixed numbers to improper fractions:

• 9 2/5 = (9 * 5 + 2) / 5 = 47/5
• 4 3/20 = (4 * 20 + 3) / 20 = 83/20

Step 2: Find a common denominator for the fractions involved, which in this case is 40:

• 5 and 8 both divide evenly into 40.

Step 3: Adjust the fractions to have the common denominator of 40:

• 47/5 becomes (47/5) * (8/8) = 376/40
• 3/8 remains as it is
• 83/20 becomes (83/20) * (2/2) = 166/40

Step 4: Perform the arithmetic operations:

• 376/40 + 3/8 - 166/40 = (376 + 3 - 166) / 40 = 213/40

Therefore, 9 2/5 + 3/8 - 4 3/20 simplifies to 213/40.
