−8/15 + 4/15
To solve this problem, we need to find the sum of -8/15 and 4/15.
Adding the numerators -8 and 4 gives -4.
Thus, the sum is -4/15.
Add −1 3/10 +(−4 2/15)
To add -1 3/10 and -4 2/15, we need to convert them into improper fractions with a common denominator.
-1 3/10 can be written as -10/10 + 3/10, which is equal to -13/10.
-4 2/15 can be written as -60/15 + 2/15, which is equal to -58/15.
Now, we can add the fractions:
-13/10 + (-58/15)
To find a common denominator, we need to find the least common multiple (LCM) of 10 and 15, which is 30.
Now, we can rewrite the fractions with a common denominator:
-13/10 = -39/30
-58/15 = -116/30
Adding the fractions:
-39/30 + (-116/30) = -155/30
The sum of -1 3/10 and -4 2/15 is -155/30, which can be further simplified to -31/6.
that's wrong
Apologies for the mistake. Let's try again.
To add -1 3/10 and -4 2/15, we need to convert them into improper fractions with a common denominator.
-1 3/10 can be written as -10/10 + 3/10, which is equal to -13/10.
-4 2/15 can be written as -60/15 + 2/15, which is equal to -58/15.
Now, we can add the fractions:
-13/10 + (-58/15)
To find a common denominator, we need to find the least common multiple (LCM) of 10 and 15, which is 30.
Now, we can rewrite the fractions with a common denominator:
-13/10 = -39/30
-58/15 = -116/30
Adding the fractions:
-39/30 + (-116/30) = -155/30
The sum of -1 3/10 and -4 2/15 is -155/30.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 5:
-155/30 = (-31 * 5)/(6 * 5) = -31/6.
To add fractions, follow these steps:
Step 1: Make sure the denominators are the same. In this case, the denominators are already the same, which is 15.
Step 2: Add the numerators together. The numerator of the first fraction is -8, and the numerator of the second fraction is 4. So, -8 + 4 = -4.
Step 3: Write the result over the common denominator. The common denominator is 15, so the sum of the fractions is -4/15.
Therefore, -8/15 + 4/15 = -4/15.
To add or subtract fractions, you need to have a common denominator. In this case, the common denominator is 15.
To calculate the sum or difference, you add or subtract the numerators and keep the denominator the same.
Let's calculate the sum:
-8/15 + 4/15
The denominators are already the same, so you can simply add the numerators:
(-8 + 4)/15 = -4/15
Therefore, -8/15 + 4/15 = -4/15
