Add the mixed numbers 4 2/5 and 1 3/4

Answer 1

4 2/5 + 1 3/4

First, convert both mixed numbers to improper fractions:

4 2/5 = (5*4 + 2) / 5 = 22/5
1 3/4 = (4*1 + 3) / 4 = 7/4

Now, add the fractions:

22/5 + 7/4

To add these fractions, we need to find a common denominator, which in this case is 20:

22/5 = 88/20
7/4 = 35/20

Now add the fractions:

88/20 + 35/20 = 123/20

Convert the improper fraction back to a mixed number:

123/20 = 6 3/20

Therefore, 4 2/5 + 1 3/4 = 6 3/20.
