Question

with what number we should multiply -31/22 so that the product is 33/20?​

Answer 1

Answer:

It’s your decision how close the the Babylonian method

you perform the operations. To be pretty authentic, to find

7/5 you would find the reciprocal of 5, which is 0;12, and

multiply that by 7. Since 7 times 12 is 60 plus 24, you’ll find

that 7/5 = 1; 24. (Alternatively, 7/5 is 1 plus 2/5, and since

1/5 is 0; 12, therefore 2/5 is 0; 24.)

For 13/15, since 1/15 is 0; 04, therefore 13/15 = 0; 52.

For 11/24, since 1/24 is half of 1/12, and 1/12 is 0; 05,

and so 1/24 is 0; 02, 30, therefore 11/24 is 11 times 0; 02, 30,

which is 0; 27, 30.

Likewise, to find 1/50, note 1/5 is 0; 12, so 1/25 =

0; 02, 24, and 1/50 = 0; 01, 12, a value you can find on the

reciprocal table. Therefore 33/50 is 33 times 0; 01, 12 which,

through a bit of computation is 0; 39, 36.
