Question

-7 2/3 + -5 1/2+ 8 3/4 PLZZZZZ HELP ME!!!!!!!!!!!!!!

Answer 1

Answer:

-53/12 or 4 5/12 either works

Step-by-step explanation:

Let's turn the mixed fractions into improper fractions.

-7 2/3 = -23/3

-5 1/2 = -11/2

8 3/4 = 35/4

Now we need to find Least Common Denominator.

12 is the LCD because

3*4 = 12 is for -23/3

2*6 = 12 is for -11/2

4*3 = 12 is for 35/4

Now you will multiply the improper fractions by the 2nd number.

$-\frac{23}{3}*(\frac{4}{4}) = -\frac{92}{12} \\\\-\frac{11}{2}*(\frac{6}{6}) = -\frac{66}{12} \\\\\frac{35}{4}*(\frac{3}{3}) = \frac{105}{12}$

Now that they have the same denominators just put the numerators in the equation.

-92 + -66 + 105 = -53

-53/12 or -4 5/12

Hope this helps ya!
