To simplify 2 4/5 - 1 2/5, we first need to convert the mixed numbers into improper fractions.
Step 1: Convert the mixed numbers to improper fractions:
2 4/5 = (2 x 5 + 4)/5 = 14/5
1 2/5 = (1 x 5 + 2)/5 = 7/5
Step 2: Subtract the two improper fractions:
14/5 - 7/5 = (14 - 7)/5 = 7/5
Step 3: Convert the resulting fraction back into a mixed number, if necessary:
7/5 can be written as 1 2/5
Therefore, 2 4/5 - 1 2/5 = 1 2/5
