Answer 1

Answer:

16/49

Step-by-step explanation:

4/7 x -3 =  - 12/21

4/7 x -5 = - 20/35

-12/21 x - 20/35 = there are 2 - symbols - x - is + answer will be in +

12/21  x  20/35 = lcm of 21 and 35 is 105

because of lcm 12/21 = 60/105

and  20/35                 = 60/105

simplify 60/105,60/105 = 4/7 and 4/7

4/7 x 4/7 = 16/49 this the answer
