Answer: 127 11/12

Step-by-step explanation:

1. 1/2 + 3/4 = 2/3

Change 1/2 by by multiplying by 2 to get a common denominator of fourths.

2/4 + 3/4 = 2/3?

5/4 = 2/3?

no

2. 5/8 - 1/4

Change 1/4 by by multiplying by 2 to get a common denominator of eighths.

5/8 - 2/8 = 3/8?

3/8 = 3/8 ?

yes

3/8 x 10 = 30/8

3. 4/5 +7/10 = 1 1/2

Change 4/5 by multiplying by 2 to get a common denominator tenths.

8/10 + 7/10 = 1 1/2?

15 /10 = 1 1/2?

yes

1 1/2 x 10 = 25

4. 2 1/3 - 1 5/6 = 1/6

Change 1/3 by multiplying by 2 to get a common denominator sixths.

2 2/6 - 1 5/6 = 1/6?

3/6 = 1/6

no

100 -2/3 - 1/6 + 30/8 + 25

multiply the thirds by 8. Sixths by 4. Eighths by 3 to get a common denomonator of 24ths.

100 - 16/24 - 4/24 + 90/ 24 + 25 = 125 70/24

create mixed number

127 22/24

reduce

127 11/12

The list that orders the fractions from least to greatest is:

  • \frac{7}{12}, \frac{2}{3}, \frac{17}{24}, \frac{3}{4}

<h3>Ordering of fractions</h3>
  • To order the fractions from least to greatest, we have to realize their conversion to decimal.
  • To realize the conversion, the numerator is divided by the denominator, as ordering decimal numbers are easier than fractions.

Hence, the fractions converted to decimal are:

  • \frac{2}{3} = 0.6667.
  • \frac{7}{12} = 0.5833.
  • \frac{17}{24} = 0.7083
  • \frac{3}{4} = 0.75

Hence, the list from least to greatest is, according to the results of the conversions:

  • \frac{7}{12}, \frac{2}{3}, \frac{17}{24}, \frac{3}{4}

Explain how to to evaluate multi-step expressions involving positive and negative decimals.
GrogVix [38]

Answer:

Hope this helps! (:

Step-by-step explanation:

By putting the numbers in the given equation,

2x + 3 + 3x = 7x + 9

5x + 3 = 7x + 9

(5x + 3) - 7x = (7x + 9) - 7x

(5x - 7x) + 3 = 9

-2x + 3 = 9

(-2x + 3) - 3 = 9 - 3

-2x = 6

-x = 3

x = -3

Therefore, our equation is correct which has a negative result.

In place of 6 if we use 8, value of x will be negative again.
