Add −12/7 + (3/14). Write your answer as a reduced improper fraction.(1 point)
It has to be in a decimal answer.
To add -12/7 + 3/14, we need to find a common denominator. The smallest common denominator between 7 and 14 is 14. So we rewrite the fractions:
-12/7 = -24/14
3/14 = 3/14
Now we can add:
-24/14 + 3/14 = -21/14
The answer as a reduced improper fraction is -21/14. However, since you want the answer in decimal form, we can divide -21 by 14:
-21 ÷ 14 = -1.5
Therefore, the decimal form of the answer is -1.5.
it's wrong
Apologies for the mistake. Let's try it again.
To add -12/7 + 3/14, we need to find a common denominator. The least common multiple (LCM) of 7 and 14 is 14.
Next, we convert the fractions to have the common denominator of 14:
-12/7 = (-12/7) * (2/2) = -24/14
3/14 = (3/14) * (1/1) = 3/14
Now we can add the fractions:
-24/14 + 3/14 = -21/14
Therefore, the sum of -12/7 + 3/14 as a reduced improper fraction is -21/14.
To write it as a decimal, we divide -21 by 14:
-21 ÷ 14 = -1.5
Therefore, the decimal form of the answer is -1.5.
-1 1/3 + (-4 2/3). (1 point)
-1 1/3 + (-4 2/3) =
To add -1 1/3 and -4 2/3, we need to convert the mixed numbers to improper fractions.
-1 1/3 is equivalent to -4/3 as an improper fraction.
-4 2/3 is equivalent to -14/3 as an improper fraction.
Now we can add the fractions:
-4/3 + (-14/3) = -4/3 - 14/3 = -18/3
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 3 in this case.
-18/3 = -6
Therefore, -1 1/3 + (-4 2/3) is equal to -6.
Add - 12/7 + (3/14). Write your answer as a reduced improper fraction. (1 point)
-12/7 + (3/14)=
To add -12/7 + 3/14, we need to find a common denominator. The least common multiple (LCM) of 7 and 14 is 14.
Next, we convert the fractions to have the common denominator of 14:
-12/7 = (-12/7) * (2/2) = -24/14
3/14 = (3/14) * (1/1) = 3/14
Now we can add the fractions:
-24/14 + 3/14 = (-24 + 3)/14 = -21/14
Therefore, -12/7 + 3/14 is equal to -21/14, which is already a reduced improper fraction.
Add -3 1/6 + 5 3/4. Write your answer as a reduced mixed number. ( 1 point)
-3 1/6 + 5 3/4=
To add -3 1/6 and 5 3/4, we first need to convert the mixed numbers into improper fractions.
-3 1/6 can be written as -19/6 as an improper fraction.
5 3/4 can be written as 23/4 as an improper fraction.
Now we can add the fractions:
-19/6 + 23/4
To find a common denominator, we need to determine the least common multiple (LCM) of 6 and 4, which is 12.
Multiplying the numerator and denominator of -19/6 by 2, we get:
-38/12
Multiplying the numerator and denominator of 23/4 by 3, we get:
69/12
Now, we can add the fractions:
-38/12 + 69/12 = 31/12
The resulting fraction, 31/12, can be simplified as a mixed number.
To simplify, we divide the numerator (31) by the denominator (12):
31 ÷ 12 = 2 remainder 7
Therefore, the sum -3 1/6 + 5 3/4 is equal to 2 7/12 as a reduced mixed number.
