Answer 2

To add the two mixed numbers -5 3/8 and 4 9/10, we need to first convert them into improper fractions.

-5 3/8 can be written as an improper fraction as follows: -5 3/8 = -((5 * 8) + 3)/8 = -43/8

4 9/10 can be written as an improper fraction as follows: 4 9/10 = ((4 * 10) + 9)/10 = 49/10

Now, we can add the fractions:

-43/8 + 49/10

To add fractions, we need a common denominator. The least common multiple (LCM) of 8 and 10 is 40.

Multiply the numerator and denominator of the first fraction (-43/8) by 5: -43/8 * 5/5 = -215/40

Multiply the numerator and denominator of the second fraction (49/10) by 4: 49/10 * 4/4 = 196/40

Now, we can add the fractions with the same denominator:

-215/40 + 196/40 = (-215 + 196)/40 = -19/40

Therefore, -5 3/8 + 4 9/10 equals -19/40.
