Please answer number 12. Very urgent!! 18 points!

Answer:

10 5/12

When the numerator is larger than the denominator, we take  groups of whole fractions  (The numerator and denominator are equal) and add 1 to the whole number for each group. Whatever remains when we no longer have the numerator larger than the denominator is left as a fraction.

Step-by-step explanation:

6 3/4 + 3  2/3

We need to get a common denominator

The common denominator is 12

We need to rename the fractional parts  to out of 12

6 3/4 = 6 3/4*3/3 = 6 9/12

3 2/3 = 3 2/3*4/4 = 3 8/12

6 9/12+ 3 8/12

9 17/12

But the numerator is larger than the denominator

We take 12/12 from the fraction  and add it to the whole number

9 17/12-12/12  +1

9+1 5/12

10 5/12

What is the value of 12x^-3 y-1 for x=-1 and y=5<br> A.-12/5<br> B.-180<br> C.-60<br> D.-5/12
Mkey [24]

Expressions are mathematical statements represented with the variables

The value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

<h3>How to determine the value of the variable</h3>

The expression is given as:

12x^{-3} y^{-1}

When x = -1, the expression becomes

12 * -1^{-3} y^{-1}

Evaluate the exponent

- 12 y^{-1}

When y = 5, the expression becomes

- 12 * 5^{-1}

Evaluate the exponent

- 12/5

Hence, the value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

Does order of numbers matter for fractions
Deffense [45]

Answer: You can see it does matter in what order you solve the equation. ... Just like when you are solving equations with whole numbers, solving equations with fractions has the same order of operations. The order of operations is the order in which you solve the problem. If numbers are in parentheses, you do them first.
