Question

by what number ⅔ be divided to get -¹⁰/²¹​

Answer 1

Answer:

-5/7

Step-by-step explanation:

let the no. by which the no. is to be divided be x

given:- (2/3)/x = -10/21

(we know, that after substituting the division sign gets changed to multiplication. Therefore, 2/3 gets changed to 3/2.)

x=  $\frac{-10}{21} *\frac{3}{2}$ = -5/7
