5/7 x -3/13
No need to find LCM because it is multiplication.
first we will multiply 5 and -3 we will get -15
Then we will multiply 7 and 13 we will get 91
so the answer is -15/91
7/11 x -3/4
first we will multiply 7 and -3 we will get -21
Then we will multiply 11 and 4 we will get 44
so the answer is -21/44
