Answer:
To add mixed numbers like these, you first need to convert them to improper fractions, which have a numerator greater than the denominator.
Four and 3/10 can be written as an improper fraction as follows:
4 + 3/10 = (4 * 10)/10 + 3/10 = 40/10 + 3/10 = 43/10.
Similarly, 2 and three on the 14th can be written as:
2 + 3/14 = (2 * 14)/14 + 3/14 = 28/14 + 3/14 = 31/14.
Now you can add these fractions by finding a common denominator and adding the numerators:
43/10 + 31/14 = (43 * 7)/(10 * 7) + (31 * 5)/(14 * 5) = 301/70 + 155/70 = 456/70.
Therefore, the sum of four and 3/10 and 2 and three on the 14th is 456/70, which can be simplified to 228/35 in lowest terms.
