Add −1310 +(−4215)

Answer 1

To add −1310 and (−4215), we simply combine the two numbers:

−1310 + (−4215) = −5525

Answer 2

Add −1 3/10 +(−4 2/15)

Answer 3

To add −1 3/10 and (−4 2/15), we need to convert the mixed numbers to improper fractions first.

−1 3/10 = -11/10

−4 2/15 = -62/15

Now, we can add the two fractions:

-11/10 + (-62/15)

To add fractions with different denominators, we need to find a common denominator. The least common multiple (LCM) of 10 and 15 is 30.

Now, we can rewrite the fractions with the common denominator of 30:

-11/10 = -33/30

-62/15 = -124/30

Now, we can add the fractions:

-33/30 + (-124/30) = -157/30

Thus, −1 3/10 + (−4 2/15) = -157/30

Answer 4

Reduce it

Answer 5

To reduce the fraction -157/30, we need to find the greatest common divisor (GCD) of the numerator and the denominator, and divide both by the GCD.

The GCD of 157 and 30 is 1.

Dividing -157 and 1 by the GCD:
-157 ÷ 1 = -157
30 ÷ 1 = 30

Therefore, the reduced form of -157/30 is -157/30.

Answer 7

To add −1 3/10 and (−4 2/15), we need to find a common denominator. The least common multiple (LCM) of 10 and 15 is 30.

Now, we can rewrite the mixed numbers as improper fractions:
−1 3/10 = -13/10
−4 2/15 = -62/15

Now, we can add the fractions:

-13/10 + (-62/15)

To add fractions with different denominators, we need to find a common denominator, which in this case is 30:

-13/10 = -39/30
-62/15 = -124/30

Now, we can add the fractions:

-39/30 + (-124/30) = -163/30

To convert the improper fraction -163/30 back to a mixed number, we divide the numerator by the denominator:

-163 ÷ 30 = -5 with a remainder of -13

Thus, the sum of −1 3/10 and (−4 2/15) is −5 13/30.

Answer 8

Add −1 2/7+(3 1/4).

Answer 9

To add −1 2/7 and 3 1/4, we need to convert the mixed numbers to improper fractions first.

−1 2/7 = -9/7

3 1/4 = 13/4

Now, we can add the two fractions:

-9/7 + 13/4

To add fractions with different denominators, we need to find a common denominator. The least common multiple (LCM) of 7 and 4 is 28.

Now, we can rewrite the fractions with the common denominator of 28:

-9/7 = -36/28

13/4 = 91/28

Now, we can add the fractions:

-36/28 + 91/28 = 55/28

Therefore, −1 2/7 + (3 1/4) = 55/28.

Answer 10

Add −1 2/7+(3/14).

Answer 11

To add −1 2/7 and 3/14, we need to convert the mixed number to an improper fraction first.

−1 2/7 = -9/7

Now we can add the fractions:

-9/7 + 3/14

To add fractions with different denominators, we need to find a common denominator. The least common multiple (LCM) of 7 and 14 is 14.

Now, we can rewrite the fractions with the common denominator of 14:

-9/7 = -18/14

3/14 = 3/14

Now, we can add the fractions:

-18/14 + 3/14 = -15/14

Therefore, −1 2/7 + 3/14 = -15/14.

Answer 12

Add −12/7+(3/14).

Answer 13

To add −12/7 and 3/14, we need to find a common denominator first. The least common multiple (LCM) of 7 and 14 is 14.

Now, we can rewrite the fractions with the common denominator of 14:

−12/7 = −24/14

3/14 = 3/14

Now, we can add the fractions:

−24/14 + 3/14 = -21/14

To simplify the resulting fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD), which in this case is 7:

-21/14 = -3/2

Therefore, −12/7 + 3/14 = -3/2.

Answer 14

Add −1 1/3+(−4 2/3)

Answer 15

To add −1 1/3 and (−4 2/3), we need to convert the mixed numbers to improper fractions first.

−1 1/3 = -4/3

−4 2/3 = -14/3

Now, we can add the two fractions:

-4/3 + (-14/3)

Now, we can add the fractions directly:

-4/3 + (-14/3) = -18/3

Simplifying the resulting fraction, we divide both the numerator and the denominator by their greatest common divisor (GCD), which is 3 in this case:

-18/3 = -6

Therefore, −1 1/3 + (−4 2/3) = -6.

Answer 16

Add −3 1/6+5 3/4. Write your answer as a reduced mixed number.

Answer 17

To add −3 1/6 and 5 3/4, we first need to convert the mixed numbers to improper fractions.

−3 1/6 = -19/6

5 3/4 = 23/4

Now, we can add the two fractions:

-19/6 + 23/4

To add fractions with different denominators, we need to find a common denominator. The least common multiple (LCM) of 6 and 4 is 12.

Now, we can rewrite the fractions with the common denominator of 12:

-19/6 = -38/12

23/4 = 69/12

Now, we can add the fractions:

-38/12 + 69/12 = 31/12

To express the resulting fraction as a mixed number, we divide the numerator by the denominator:

31 ÷ 12 = 2 with a remainder of 7

Thus, the sum of −3 1/6 and 5 3/4 is 2 7/12.
