Question

do these two questions (a) ,(b) with full solution​

Answer 1

Answer:

a) 32/15

b) 228/91

Step-by-step explanation:

b) Let the no. which is to be subtracted be = x

27/13 - x = -3/7

on replacing -3/7 to the left side it will become postive 3/7

27/13 + 3/7 = x

LCM of 13 and 7 = 91

27/13*7 + 3/7 *13 = x

189/91 + 39 / 91 = x

ans= 228/91

Answer 2

a) let the number be ‘x’

By Condition ,

x + (-5/3) =2/5

or, x = 2/5 - (-5/3)

or, x = 6+25/15

or, x = 31/15

If you want to check the ans add this with (-5/3)

31/15 + (-5/3)

= 31-25/15

= 6/ 15 = 2/5

so, it is proved

I hope this will help you
