Question

1.Subtract the sum of -8/9 and 3/2 from the sum of 11/-18 and -1/36.

2.Subtract the sum of 2 3/7 and
-5 4/7 from the difference of 4/15 and -2/5.​

Answer 1

Answer:

➪-8/9 + 3/2. ➪ 11/-18 + ( -1/36 )

-16 + 27 / 18 11/-18 - 1/36

11/18. - 22 - 1 / 36

-23/36

➪ -23/36 - 11/18

-23 - 22/ 36

-45/36 = -15/12

➪ 17/7 + ( -39/7 ) ➪ 4/15 + ( -2/5 )

17/7 - 39/7. 4/15 - 2/5

17 - 39/7. 4 - 6/15

-22/7. -2/15

➪ -2/15 - ( -22/7 )

-2/15 + 22/7

-14 + 330 /105

-316/105

Answer 2

Answer:

1) -5/12

Step-by-step explanation:

LCM of 3 and 9 = 9

= -8/9 + 2*3/3*3

= -8/9 + 6/9 [Writing the fractions with common denominator]

= -8 + 6/9

= -2/9

11/-18 = 11*-1/-18*-1 [Converting into standard form ]

= -11/18

LCM of 18 and 36 = 36

= -11*2/18*2 + (-1/36)

= -22/36 + (-1/36) [Writing the fractions with common denominator]

= -22+(-1) /36

= -22 - 1/36

= -23/36

Now we have ge numbers -2/9 and -23/36

A.T.Q

We have to subtract -2/9 from -23/36

= -23/36 - (-2/9)

LCM of 36 and 9 = 36

= -23/36 -(-2*4/9*4)

= -23/36 -(-8/36)

= -23-(-8) /36

= -23 + 8/36

= -15/36 = -5/12
