Question

By what number should -55/18 be divided to get -22/9​

Answer 1

Answer:

Let the required number be x.

x/(-55/18) = -22/9

-55/18 * 1/x(as division of x will be 1/x or u can say reciprocal of x) = -22/9

-55/18x = -22/9

now we can cross multiply (multiplying -55 by 9 and multiplying 18x by -22)

-55*9 = -22*18x

-495 = -396x

- sign will be cancelled out as it equal to the other part or we can say it will be cancelled with each other because while dividing they will cancel each other.

x = 495/396

x = 5/4

Hence the required number is 5/4
