- 1 3/10 + (-4 2/15)
To add -1 3/10 and -4 2/15, we need to find a common denominator. The least common multiple of 10 and 15 is 30.
-1 3/10 can be written as -13/10 in fraction form, and -4 2/15 can be written as -62/15.
Now, we can add the fractions:
-13/10 + (-62/15) = (-13 * 3)/(10 * 3) + (-62 * 2)/(15 * 2)
= -39/30 + (-124/30)
= -163/30
Therefore, the sum of -1 3/10 and -4 2/15 is -163/30.
-1 3/10 can be written as -13/10 in fraction form, and -4 2/15 can be written as -62/15.
Now, we can add the fractions:
-13/10 + (-62/15) = (-13 * 3)/(10 * 3) + (-62 * 2)/(15 * 2)
= -39/30 + (-124/30)
= -163/30
Therefore, the sum of -1 3/10 and -4 2/15 is -163/30.
