Add −127+(314). Write your answer as a reduced improper fraction
To add -12/7 and 3/14, we need to find a common denominator. The least common multiple of 7 and 14 is 14.
-12/7 + 3/14 = -24/14 + 3/14
Now that we have a common denominator, we can add the numerators:
= (-24 + 3)/14
= -21/14
To reduce this fraction, we can divide the numerator and denominator by their greatest common divisor, which is 7.
-21/14 = (-21 ÷ 7)/(14 ÷ 7)
= -3/2
Therefore, the sum is -3/2.
To add 13.92 and -22.111, we simply add the two numbers together:
13.92 + (-22.111) = -8.191
Therefore, the sum is -8.191.
To add -127 and 314, we add the two numbers together.
-127 + 314 = 187
Therefore, the sum is 187.
To add -1 1/3 and -4 2/3, we first need to convert the mixed numbers into improper fractions.
-1 1/3 can be written as -4/3.
-4 2/3 can be written as -14/3.
Now, we can add the two fractions:
-4/3 + (-14/3) = (-4 - 14)/3 = -18/3 = -6.
Therefore, the sum is -6.
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.
5 3/4 can be written as 23/4.
Now, we can add the two fractions:
-19/6 + 23/4 = (-19*2)/(6*2) + (23*3)/(4*3) = -38/12 + 69/12 = 31/12.
To write the answer as a reduced mixed number, we divide the numerator (31) by the denominator (12):
31 ÷ 12 = 2 remainder 7.
Therefore, the sum is 2 7/12.
To add -5.11 and -1.56, we simply add the two numbers together:
-5.11 + (-1.56) = -6.67
Therefore, the sum is -6.67.
To add -8/15 and 4/15, we add the numerators and keep the same denominator:
-8/15 + 4/15 = (-8 + 4) / 15 = -4 / 15
Therefore, the sum is -4/15.
To add -1 3/10 and -4 2/15, we first need to convert the mixed numbers into improper fractions.
-1 3/10 can be written as -13/10.
-4 2/15 can be written as -62/15.
Now, we can add the two fractions:
-13/10 + (-62/15) = (-13*3)/(10*3) + (62*2)/(15*2)
= -39/30 + -124/30
= -163/30
To write the answer as a mixed number, we divide the numerator (163) by the denominator (30):
163 ÷ 30 = 5 remainder 13
Therefore, the sum is -5 13/30.
To add -1.2 and 7.6, we simply add the two numbers together:
-1.2 + 7.6 = 6.4
Therefore, the sum is 6.4.
To add -4.85 and -2.54, we simply add the two numbers together:
-4.85 + (-2.54) = -7.39
Therefore, the sum is -7.39.
