Add - 1 3/15 + (-4 2/15)
To add - 1 3/15 and -4 2/15, we can first convert the mixed numbers into improper fractions.
-1 3/15 can be written as -1 + 3/15 = -1 + 1/5 = -5/5 + 1/5 = -6/5.
-4 2/15 can be written as -4 + 2/15.
Now we can add the fractions:
-6/5 + (-4 + 2/15)
To add these fractions, we need to find a common denominator. The common denominator in this case is 5 * 15 = 75.
Multiplying the numerator and denominator of -6/5 by 15, we get -90/75.
Multiplying the numerator and denominator of -4 + 2/15 by 5, we get -20/75 + 2/15 = -20/75 + 10/75 = -10/75.
Now we can add the fractions:
-90/75 + (-10/75) = -100/75 = -4/3.
Therefore, -1 3/15 + (-4 2/15) = -4/3.
To add -1 3/15 and -4 2/15, follow these steps:
Step 1: Convert the mixed numbers to improper fractions.
-1 3/15 = -(1*15 + 3)/15 = -18/15
-4 2/15 = -(4*15 + 2)/15 = -62/15
Step 2: Add the fractions.
-18/15 + (-62/15) = (-18 - 62)/15 = -80/15
Step 3: Simplify (if possible).
-80/15 = -(80/5)/(15/5) = -16/3
So, -1 3/15 + (-4 2/15) = -16/3.
