Add −127+(314). Write your answer as a reduced improper fraction.(1 point)
−127+(314)=
GPT 3.5
−127 + 314 = 187

Therefore, the sum is 187.
Add −12/7+(3/14). Write your answer as a reduced improper fraction.(1 point)
−12/7+(3/14)=
GPT 3.5
To add fractions, we need to find a common denominator. In this case, the common denominator is 14.

−12/7 + 3/14 = −(12 * 2)/(7 * 2) + 3/14

= −24/14 + 3/14

Next, we can combine the numerators:

= (−24 + 3)/14

= −21/14

Therefore, the sum is −21/14, which is already in reduced form.
Add −1 1/3+(−4 2/3). (1 point)
−1 1/3+(−4 2/3)=
GPT 3.5
To add mixed numbers, we first need to convert them to improper fractions.

−1 1/3 = −4/3
−4 2/3 = −14/3

Now we can add the fractions:

−4/3 + (−14/3) = (−4 − 14)/3

= −18/3

Simplifying the fraction, we have:

−18/3 = −6

Therefore, the sum is −6.
Add −3 1/6+5 3/4. Write your answer as a reduced mixed number.(1 point)
−3 1/6+5 3/4
GPT 3.5
To add mixed numbers, we first need to convert them to improper fractions.

−3 1/6 = −19/6
5 3/4 = 23/4

Now we can add the fractions:

−19/6 + 23/4
= (−19*2)/(6*2) + 23/4
= −38/12 + 23/4

Next, we find a common denominator, which is 12:

−38/12 + 23/4
= −38/12 + (23*3)/(4*3)
= −38/12 + 69/12

Now we can add the numerators:

(−38 + 69)/12 = 31/12

Since the numerator (31) is larger than the denominator (12), we have a mixed number. Dividing 31 by 12, we determine the whole number and the remainder:

31 ÷ 12 = 2 remainder 7

Therefore, the sum is 2 7/12, which is the reduced mixed number.
