Question

1.?
3. By what rational number should -12 1÷2 be divided to get 1 7÷8​

Answer 1

Step-by-step explanation:

-12*1/2 ÷ X = 1*7/8

= - 25/2 ÷ X = 15/8

= - 25/2 × 1/X = 15/8

= 1/X = 15/8 × 2/-25

= 1/X = 3/4 × - 1/5

= 1/X = - 3/20

= - 3x = 20

= x = - 20/3

So the rational number is - 20/3
