Question

-m=-6 3/8+5 1/8 -k=11+(-12,3) -y= -13+(-8 5/12)

Answer 1

-m=-1 2/8
-m=-1 1/4
m=1 1/4
$$$$$$$$$$
-k=11-12.3
-k=-1.3
k=1.3
$$$$$$$$$$$$
-y=-13-8 5/12
-y=-21 5/12
y=21 5/12

Answer 2

To simplify the expressions you provided, let's evaluate each one step by step:

1. For -m = -6: The value of -m is -6.

2. For 3/8 + 5 1/8: To add these fractions, we need to find a common denominator, which in this case is 8. The expression becomes (3/8 + 41/8), where both fractions have the same denominator. Adding the numerators gives us 44/8. Simplifying the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 11/2 or 5 1/2.

   Therefore, 3/8 + 5 1/8 is equal to 5 1/2.

3. For -k = 11 + (-12,3): It seems there might be a typo in the expression you provided. If you meant to subtract -12.3 from 11, we can do that: -k = 11 - 12.3. Subtracting 12.3 from 11 gives us -1.3.

   Therefore, -k = -1.3.

4. For -y = -13 + (-8 5/12): To simplify this expression, we need to convert the mixed number -8 5/12 to an improper fraction. Multiplying the whole number (8) by the denominator (12) and adding the numerator (5), we get 101/12. The expression then becomes -13 + (-101/12). To add these fractions, we need to find a common denominator, which in this case is 12. The expression becomes (-156/12 + (-101/12)), where both fractions have the same denominator. Adding the numerators gives us -257/12.

   Therefore, -y = -257/12.

Summary:

• m = -6
• 3/8 + 5 1/8 = 5 1/2
• -k = -1.3
• -y = -257/12
