Answer 3

The correct answer is 5 1/2.

To add the mixed numbers 4 2/5 and 1 3/4, you first convert them both to improper fractions.

4 2/5 = 22/5
1 3/4 = 7/4

Then add the fractions together:

22/5 + 7/4 = (22/5) + (35/20) = (88/20) + (35/20) = 123/20

Finally, convert the improper fraction back to a mixed number:

123/20 = 6 3/20

So, the sum of 4 2/5 and 1 3/4 is 5 1/2.

Answer 5

I apologize for the mistake in my previous response. Let's re-calculate:

4 2/5 = 22/5
1 3/4 = 7/4

Now, add the fractions together:

22/5 + 7/4 = (22*4)/(5*4) + (7*5)/(4*5)
= 88/20 + 35/20
= 123/20

Finally, convert the improper fraction back to a mixed number:

123/20 = 6 3/20

So, the sum of 4 2/5 and 1 3/4 is indeed 6 3/20. Thank you for your patience.
