Answer 2

Answer:

Step-by-step explanation:

hey bro here's ur answer

1/7 * ( -2/9 ) * 14/15 * 18/12

              1260

1/7 * ( -2/9 ) * 14/15 * 18/12

180 * ( -280 ) * 1176 * 1890

             1260

 180   * -280 * 1176 * 1890

1260     1260   1260   1260

putting everything  in the ascending order but u can put it in descending order too

-280 < 180 < 1176 < 1890

1260   1260    1260   1260

-2 < 1 < 14 < 18                    ( actual numbers )

9     7    15    12

solving

-2/9 * 1/7 * 14/15 * 18/12

-2 and 12 gets cancled

9 and 18 gets cancled

7 and 14 get cancled

in the numerator we r left with -2 and 2

in the denomenator we r left with 15 and 6

so we get -4/ 90

-4 and 90 gets cancled by 2

we get  -2/ 45
