-1/3/10 + - 4/2/15
To add -1/3/10 and -4/2/15, we first need to find a common denominator. In this case, the common denominator is 30.
-1/3/10 = -10/30
-4/2/15 = -30/30
Now we can add the two fractions:
-10/30 + -30/30 = -40/30
Simplifying the fraction by dividing both the numerator and the denominator by their greatest common divisor, we get:
-40/30 = -4/3
To add the given fractions, we need to make sure they have the same denominator.
The first fraction is -1/3/10, which we can rewrite as -1/30.
The second fraction is -4/2/15, which we can simplify as -2/15.
Now, we can add the fractions:
-1/30 + -2/15
To add fractions, we need a common denominator. The smallest number that both 30 and 15 divide into is 30.
So, we'll convert both fractions to have a denominator of 30:
-1/30 = -1 * (30/30) = -30/30
-2/15 = -2 * (2/2) = -4/30
Now, we can add the fractions:
-30/30 + -4/30 = (-30 - 4) / 30 = -34/30
However, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:
-34/30 = -17/15
Therefore, the sum of -1/3/10 and -4/2/15 is equal to -17/15.
