Subtract
-6-(-2)=8 is this right I get confused.
add. -5/14+9/7=-14/21
No to your first question.
-6-(-2)= -6 + 2 = __
No to your second question, also.
The common denominator to use is 14.
-5/14 + 9/7 = -5/14 + 18/14 = (18-5)/14
= 13/14
To subtract -6 - (-2), you can use the following steps:
1. Simplify the double negative by changing -(-2) to +2:
-6 - (-2) = -6 + 2
2. Add the numbers together to find the result:
-6 + 2 = -4
So, the correct answer is -4.
Now, let's solve the addition problem: -5/14 + 9/7. To add fractions, you need a common denominator.
1. Determine the least common multiple (LCM) of the denominators (14 and 7). In this case, the LCM is 14.
2. Convert the fractions to have a denominator of 14:
-5/14 = -5 * (14/14) = -70/14
9/7 = 9 * (2/2) = 18/14
3. Now that both fractions have a common denominator, add the numerators together:
-70/14 + 18/14 = (-70 + 18)/14 = -52/14
4. Simplify the fraction, if possible. In this case, the numerator (-52) and denominator (14) share a common factor of 2:
-52/14 = (-26 * 2)/(7 * 2) = -26/7
Therefore, the result of -5/14 + 9/7 is -26/7 or -14/21 when in simplified form.
