Question

solve a)4+7/8 b)9/11-4/15 c)8/1/2-3/5/8​

Answer 1

Solutions:

a) 4 + 7 / 8

= 4 / 1 + 7 / 8

= 32 + 7 / 8      (Their LCM is 8)

= 39 / 8

= 4 whole 7 / 8

b) 9 / 11 - 4 / 45

= 405 - 44 / 495   (Their LCM is 495)

= 361 / 495

Answer 2

Answer:

a) 39/8   b) 11/15   c) 39/8

Step-by-step explanation:

a) 4+ (7/8)

L.C.M. of denominatore = 8

4 = (4 × 8)/8 = 32/8

4+  (7/8)

= (32+7)/8

= 39/8

------------------------------------------

b) 9/11- (4/15)

L.C.M of denomiators- 165

9/11 × 15/15

= 135/165

4/15 × 11/11

=44/165

9/11-(4/15)

= (165-44)/165

= 11/15

----------------------------------------

c) 8 1/2 - 3 5/8​

8 1/2 = 17/2

3 5/8 = 29/8

L.C.M of denomiators = 8

17/2 × 4/4 = 68/8

8 1/2 - 3 5/8​

= (68-29)/8

= 39/8
