Add −1 3/10 +(−4 2/15).(1 point)
To add -1 3/10 and -4 2/15, we need to find a common denominator and then add the fractions.
The common denominator is 30.
-1 3/10 is equal to -10/10 + 3/10 = -13/10
-4 2/15 is equal to -60/15 + 2/15 = -58/15
Now we can add the fractions:
-13/10 + -58/15
To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 30.
To convert -13/10 to have a denominator of 30, we multiply the numerator and denominator by 3:
(-13/10) * (3/3) = -39/30
To convert -58/15 to have a denominator of 30, we multiply the numerator and denominator by 2:
(-58/15) * (2/2) = -116/30
Now we can add the fractions:
-39/30 + -116/30 = -155/30
Simplifying the fraction, we get:
-155/30 = -31/6
Therefore, the result of -1 3/10 + -4 2/15 is -31/6.
ugh
I apologize if my response was confusing. Let's try solving the problem step by step:
To add -1 3/10 and -4 2/15, we first need to convert the mixed numbers into improper fractions.
-1 3/10 = -1 * 10/10 + 3/10 = -10/10 + 3/10 = -13/10
-4 2/15 = -4 * 15/15 + 2/15 = -60/15 + 2/15 = -58/15
Now that we have both fractions with the same denominator, we can add them:
-13/10 + (-58/15)
To add the fractions, we need to find a common denominator. In this case, the least common multiple of 10 and 15 is 30.
Converting -13/10 and -58/15 to have a denominator of 30:
-13/10 * 3/3 = -39/30
-58/15 * 2/2 = -116/30
Now we can add the fractions:
-39/30 + (-116/30) = -155/30
Simplifying the fraction, we get:
-155/30 = -31/6
Therefore, the sum of -1 3/10 and -4 2/15 is -31/6.
