-8/15 + 4/15
To add -8/15 and 4/15, you simply add the numerators to get -8 + 4 = -4, and keep the same denominator of 15. Therefore, the sum is -4/15.
-1 3/10 + (-4 2/15) = ?
To add -1 3/10 and -4 2/15, first convert both mixed numbers to improper fractions:
-1 3/10 = (-1 × 10 + 3)/10 = -13/10
-4 2/15 = (-4 × 15 + 2)/15 = -62/15
Now, we can add the fractions:
-13/10 + (-62/15)
Since the denominators are different, we need to find a common denominator which is the least common multiple (LCM) of 10 and 15, which is 30.
-13/10 = -39/30 (multiply numerator and denominator by 3 to get a denominator of 30)
-62/15 = -124/30 (multiply numerator and denominator by 2 to get a denominator of 30)
Now we can add the fractions:
-39/30 + (-124/30) = -163/30
So, -1 3/10 + (-4 2/15) = -163/30.
add -1 3/10 + (-4 2/15).(1 point)
