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.
-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.
