Add - 1 3/10 + (-4 2/15

Answer 1

To add -1 3/10 and -4 2/15, we first need to find a common denominator.

The denominator for 10 and 15 is 30.

-1 3/10 can be rewritten as -10/10 + 3/10 = -13/10.

-4 2/15 can be rewritten as -60/15 + 2/15 = -58/15.

Now, we can add the fractions:

-13/10 + (-58/15)

To add these fractions, we need a common denominator, which is 30:

-13/10 * 3/3 = -39/30
-58/15 * 2/2 = -116/30

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

-39/30 + (-116/30) = -155/30

Simplifying the result, we get:

-155/30 = -5 5/6
