Hey simplifying one algebra problem?

Question

-5/12 + 1 5/8 + (-6 3/10)

Answer 1

To add fractions they need to have a common denominator

-5/12 =[ 10 * (-5) ] / (10 * 12) = -50/120

1 5/8 = 13/8 = (15 * 13) / (15 * 8) = 195/120

-6 3/10 = -63/10 = (12 * (-63)) / (12 * 10) = -756/120

-5/12 + 1 5/8 + (-6 3/10) =

-50/120 + 195/120 - 756/120 =

(-50 + 195 - 756)/120 =

-611 / 120 =

-5 11/120

Answer 2

convert all the denominators to the same thing:

-100/240 + 240/240 + 150/240  -1440/240 - 72/240 = -1022/240

Simplify: -1222/240 = -611/120

Answer 3

-5/12 + 1 5/8 + (-6 3/10)

Change to all fractions (not mixed):

= -5/12 + 13/8 - 63/10

Find LCD:

12 = 2 x 2 x 3

8 = 2 x 2 x 2

10 = 2 x 5

LCD = 2 x 2 x 2 x 3 x 5 = 120

-5/12 = -50/120

13/8 = 195/120

-63/10 = -756/120

-50/120 + 195/120 - 756/120

= (-50 + 195 - 756)/120

= -611/120

= -5 11/120

Answer 4

-5/12 + 1 5/8 + (-6 3/10) (change mixed numbers to improper fractions)

-5/12 + 13/8 - 63/10 (find the least common denominator of 12, 8, and 10, which is 120)

-5/12*10/10 + 13/8*15/15 - 63/10*12/12

-50/120 + 195/120 - 756/120 (add and subtract numerators)

-611/120 or -5 11/120 <===ANSWER

Answer 5

You have to find a common denominator. I believe the answer is -307/60

Answer 6

12=3*2*2

8=2*2*2

10=5*2

then you need 5*3*2*2*2=10*12=120

You will multiply by

120/12=10

120/8=40*3/8=5*3=15

120/10=12

-50/120 + 1 75/120 + (-6 36/120)

Separate the integers

1-6 + (75-50-36)/120 = -5 - (11/120)

=- 5 11/120 = -611/120
