Question

From what number should -8/21 be subtracted to get 29/63

Answer 1

Answer:

5/8

Step-by-step explanation:

let -8/12  be subtracted from x to get 29/63

x-(-8/21)=29/63

x+8/21=29/63

x=29/63-8/21

=29/63-24/63

=1/63*(29-24)

=5/63

Answer 2

Solution:

Let x should be subtracted from -8/21 to get 29/63

-8/21 - x = 29/63

=> -x = 29/63 + 8/21

=> -x = 29/63 + (8×3)/(21×3)

=> -x = 29/63 + 24/63

=> -x = 29/63 +24/63

=> -x = (29+24)/63

=> -x = 53/63

=>x = -53/63
