Add -1 3/10+ -4 2/15
To add mixed numbers, you first need to convert them into improper fractions. Let's convert -1 3/10 and -4 2/15 into improper fractions.
-1 3/10 can be written as -(1*10 + 3)/10 = -13/10.
-4 2/15 can be written as -(4*15 + 2)/15 = -62/15.
Now, we can add the fractions:
-13/10 + (-62/15)
To add fractions with different denominators, we need to find a common denominator. The common denominator for 10 and 15 is 30.
Multiply -13/10 by 3/3 to get -39/30.
Multiply -62/15 by 2/2 to get -124/30.
Now, we can add the fractions:
-39/30 + (-124/30) = (-39 - 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 -(1*10 + 3)/10 = -13/10.
-4 2/15 can be written as -(4*15 + 2)/15 = -62/15.
Now, we can add the fractions:
-13/10 + (-62/15)
To add fractions with different denominators, we need to find a common denominator. The common denominator for 10 and 15 is 30.
Multiply -13/10 by 3/3 to get -39/30.
Multiply -62/15 by 2/2 to get -124/30.
Now, we can add the fractions:
-39/30 + (-124/30) = (-39 - 124)/30 = -163/30.
Therefore, the sum of -1 3/10 and -4 2/15 is -163/30.
