Add −815 + 415 would give the answer of -400.
Add −8/15+4/15
To add -8/15 and 4/15, we combine the numerators while keeping the denominator the same:
-8/15 + 4/15 = (-8 + 4)/15
This simplifies to:
-4/15
Add −1/3/10 +(−4/2/15).
To add -1/3/10 and -4/2/15, we need to find a common denominator. The denominators in this case are 10 and 15, and the least common multiple of 10 and 15 is 30.
Next, we convert both fractions to have a denominator of 30:
-1/3/10 = -1 * (30/10) = -3/1/30 = -3/30
-4/2/15 = -4 * (2/15) = -8/1/30 = -8/30
Now, we can add the fractions:
-3/30 + (-8/30) = (-3 - 8)/30 = -11/30
Therefore, -1/3/10 + (-4/2/15) = -11/30.
-12over7+(3over14)
To add -12/7 and 3/14, we need to find a common denominator. The least common multiple of 7 and 14 is 14.
Next, we convert both fractions to have a denominator of 14:
-12/7 = -12 * (2/2) / 7 = -24/14
3/14 = 3 * (1/1) / 14 = 3/14
Now, we can add the fractions:
-24/14 + 3/14 = (-24 + 3)/14 = -21/14
Therefore, -12/7 + 3/14 = -21/14.
